I have lost the original article. Rec articles disappear quickly here. It is of ABSOLUTELY no interest to non-builders, so skip now, or face another 200 lines. In most cases, you will need more than one catalogue, particularly if you build from scratch, as against modifying existing components. Sorry this is so long, but the detail may prove useful to some. The places from which I buy most of my parts are, in no particular order : 1. Old Colony Sound Labs PO Box 243 Peterborough, NH 03458 (603) 924-6371 (9-4, M-F) Corning and Resista resistors, Wima and Flable (?) polypropylene capacitors. Both are in rectangular packages, with short leads, perfect for pcb's, particularly if you lay them out and etch them yourself, less convenient for placing across power caps, i.e. you have to do the work of attaching longer leads. The Wimas are compact, and I have been quite happy with them. OCSL sells pcb's, parts, and full kits, for a wide range of projects from Audio Amateur and Speaker Builder. They have decent prices on resistors and capacitors, miserable prices on semiconductors. However, full kits seem not unreasonably priced, i.e. the markup on semiconductors seems to be less in kits. They charge no shipping, in most cases, except for some massively heavy items, like class A amp kits with multi-ton transformers. Service is spectacularly good, and almost any problem can be resolved over the telephone. However, they won't take resistor and capacitor orders over the telephone, as a matter of policy, to avoid misspecification. Also, it is a good idea to avoid giving them separate shipping and mailing addresses; they seem to have trouble with that. If these caveats seem to compromise my claim that service is extraordinary, I deny that. Experience will make a believer of anyone. 2. Audio Concepts 901 S. 4th Street La Crosse, WI 54601 (608) 784-4570 Wonder Caps, Chateauroux caps (reasonably priced for large value polyprops) loudspeaker parts and kits. Well-informed people, even if they do cater to the fringe lunatic to some small extent (like sixty-zillion-dollar-an-ounce Wonder Solder; I can understand paying for decent 63/37 eutectic stuff instead of 60/40, but there are limits ....). But I don't blame them for market realities. If people want it, etc. The Chateauroux caps have long, flexible leads, and are physically fairly large. Pcb use would require supports. Good value, though. 3. Madisound Speaker Components 8608 University Green Madison, WI 53711 (608) 831-3433 Sidereal capacitors, speaker components. I have not used the Sidereals, but many people swear by them. 4. Precision Audio Supply Box 96 Downey, CA 90241 (213) 869-6804 Does anyone know if they are still around? I have not had luck recently calling them. If they are still in business, they are an excellent source of close tolerance polystyrenes, and lots of polypropylenes, and of some tube related stuff. An update on a recent posting : Precision Audio Supply PO Box 96 Downey, CA 90241 (213) 869-6804 (10:30-4, PST, closed on Wednesdays) These people are still around; I spoke to them today. PAS is the best place I know of for small polystyrene and polypropylene capacitors, including 1% and 2% tolerance items. Rather comprehensive. They also sell other stuff, of rather high quality. Good place. -------------------------------------------------------------------------- Shankar Bhattacharyya, Information Systems, New York University shankar@rnd.gba.nyu.edu -------------------------------------------------------------------------- 5. Newark Electronics Headquarters in Chicago, I believe, at (312) 784-5100. Offices everywhere. Complete line of Motorola, TI, etc. Your basic general purpose electronics distributor. Minimum order of $25 for credit card purchases. Ask for a catalogue if you don't already have one. Vastly useful. They don't seem to sell National Semiconductor devices. Pity. I need some yesterday - I think I've blown some fets. 6. Digi-Key Corporation 701 Brooks Ave. South PO Box 677 Thief River Falls, MN 56701 (800) 344-4539 Good source for capacitors, resistors, diodes, commonplace semiconductors. Not comprehensive, but prices are reasonable. They sell a good line of Panasonic electrolytics. Every builder needs their catalogue. 7. Mouser Electronics PO Box 699 Mansfield, TX 76063 (800) 346-6873 Reasonable selection of items, with odd blank spots. Terrific source of reasonably priced non-sexy items, like the hardware to put a project together. One does need more than polypropylene capacitors and metal film resistors. Want a gold-plated TO3 socket? About a buck. You have to watch out for their tendency to send stuff in small batches, as they become available, and to charge you for each shipment. Check availability in advance, or shipping costs will surprise you. Then there are places which specialize in Japanese devices like the Toshiba and Hitachi fets and MOSFETS. 8. Ora Electronics 20120 Plummer St. PO Box 4029 Chatsworth, CA 91313 9. East Coast Transistor 2 Marlborough Road W. Hempstead, NY 11552 (516) 483-0388 Ora and East Coast carry the Japanese fets which have seen wide use of late; 2SK, 2SJ, 2SA, 2SB, 2SD, etc. Getting data sheets is another matter. Hitachi's semiconductor division is at (800) 262-1502, or possibly (201) 262-1502. They can refer you to a representative, who can refer you to a distributor. Ask the representative for a copy of Hitachi's Power Mosfet Data Book, publication D11. You may also be able to get this from Hitachi's literature people, but it may be more trouble than you expect. Unless you know EXCATLY what you need, and I don't, it is very hard to get the Japanese semiconductor manufacturers to get data books to you. Most are set up in the USA as consumer electronics companies, not device manufacturers, and I have had to persuade them that they do, in fact, make the devices in which I have been interested. 10. GSI Musical Electronics 228 Washington Ave Belleville, NJ 07109 (201) 751-7505 (11-6, M-F) Tube related stuff, but I don't know much about their range of stuff. High voltage caps should be available. They are big on Dyna ST-70's. They supply a fair range of good tubes, I believe, and assorted amps and preamps of their own design. For the remaining places I don't have addresses handy, but others will: 11. The Tweak Shop They cater to the fringe lunatics, with fancy cable, connectors, etc., in addition to good caps and resistors. I saw a catalog once. If you look carefully, you can probably find useful stuff from a builder's point of view. Pricey. There are other places like the Tweak Shop, and I expect others on the net know about them. They are all outside my price range, and I have not dealt with any of them. 12. Douglas Kent Smith Consulting (or some such name). He provides high-quality tubes and assorted technical information on their use. I don't know any more. 13. Audio Research Corporation Minneapolis, MN They are in the book, obviously. They will sell parts at not terrible prices, and are obviously a good source of parts for tube projects. I believe they will sell you anything except their output transformers and their analog-modules, whatever the hell those are. They sell noise selected tubes, matched pairs, and so on. 14. Stereo Cost Cutters They bought out the entire Dynaco stock, and are the principal source of parts for them, including the output transfromer for the ST-70. However, since you can buy a used ST-70 for about the price of the transformers, I am not sure how good a deal they represent. Still, if you are into Dynaco, their supply of parts and manuals is invaluable. Finally, there are a few surplus places, which are worth exploring. Their stock is often odd, and very erratic, but I have picked up various valuable items for very little. Of course, when you include the junk I acquired, the average cost may or may not be a whole lot lower than usual : Star Tronics (I picked up single-deck Alps pots for $3.50 each) BNF All Electronics Corporation (very useful source of electrolytics, hardware, relays) I have not dealt with these places in some time, and I don't know if they are still around. I expect they are. And, absolutely finally : Elcon Sales 470 Clifton Avenue Clifton, NJ 07011 is an apparently mom-and-pop manufacturing operation which makes capacitors for the defense industry, including polypropylenes. They maintain something called an "off-price line" or some such thing, which consists of caps which are out of spec in some trivial way, like being 21% off nominal value and so on, which they sell for much less than list. For bypass use and so on it obviously does not matter. They have a strong tendency to use copper-clad steel leads, if you are concerned about that sort of thing. If you receive useful e-mail responses, please post. I am sure we builders would love a comprehensive list. >From bill@vrdxhq.verdix.com (William Spencer) Mon Feb 25 13:59:16 1991 Path: paul.rutgers.edu!aramis.rutgers.edu!dimacs.rutgers.edu!bcm!cs.utexas.edu!wuarchive!zaphod.mps.ohio-state.edu!rpi!uupsi!grebyn!vrdxhq!bill From: bill@vrdxhq.verdix.com (William Spencer) Newsgroups: rec.audio,rec.music.makers Subject: LIST: parts, magazines, service Message-ID: <47230@vrdxhq.verdix.com> Date: 25 Feb 91 18:59:16 GMT Followup-To: rec.audio Distribution: na Organization: Verdix Corporation, Chantilly, VA Lines: 305 Send corrections, additions ,comments, experiences to bill@verdix.com --------------------------------------------------------------------- LOUDSPEAKER COMPONENTS ====================== Music Stores: Typically Gauss, JBL, Electro-Voice, Fostex "pro" components, Celestion guitar speakers.

I have no intellectual obsessions about what you deem appropriate for such a list. Here goes: =========================================================================== This list of sources for parts is compiled from my own list of sources, and from contributions from Bill Spencer, Len Moskowitz, John Allen, Bob Sluggs, and probably others on the net.

They sell a few lunatic fringe items, (like sixty-zillion-dollar-an-ounce Wonder Solder; I can understand paying for decent 63/37 eutectic stuff instead of 60/40, but there are limits ....). But that is not representative of what they do. They are pragmatic people, with a good line of products, and one can buy a design manual for any of their speakers for a reasonable price. The Chateauroux caps have long, flexible leads, and are physically fairly large. Pcb use would require supports. Good value, though.

Ask for a catalogue if you don't already have one. They don't seem to sell National Semiconductor devices. Pity. The National LM334 and 336 are useful devices, as are many others. ***************** Digi-Key Corporation 701 Brooks Ave. South PO Box 677 Thief River Falls, MN 56701 (800) 344-4539 Good source for capacitors, resistors, diodes, commonplace semiconductors. Not comprehensive, but prices are reasonable. They sell a good line of Panasonic electrolytics. Every builder needs their catalogue. ***************** Mouser Electronics PO Box 699 Mansfield, TX 76063 (800) 346-6873 Reasonable selection of items, with odd blank spots. Terrific source of reasonably priced non-sexy items, like the hardware to put a project together. One does need more than polypropylene capacitors and metal film resistors. Want a gold-plated TO3 socket? About a buck. You have to watch out for their tendency to send stuff in small batches, as they become available, and to charge you for each shipment. Check availability in advance, or shipping costs will surprise you. ***************** Then there are places which specialize in Japanese devices like the Toshiba and Hitachi fets and MOSFETS. Ora Electronics 20120 Plummer St. PO Box 4029 Chatsworth, CA 91313 East Coast Transistor 2 Marlborough Road W. Hempstead, NY 11552 (516) 483-0388 Ora and East Coast carry the Japanese fets which have seen wide use of late; 2SK, 2SJ, 2SA, 2SB, 2SD, etc. Getting data sheets is another matter. Hitachi's semiconductor division is at (800) 262-1502, or possibly (201) 262-1502. They can refer you to a representative, who can refer you to a distributor. Ask the representative for a copy of Hitachi's Power Mosfet Data Book, publication D11. You may also be able to get this from Hitachi's literature people, but it may be more trouble than you expect. Unless you know EXACTLY what you need, and I don't, it is very hard to get the Japanese semiconductor manufacturers to get data books to you. Most are set up in the USA as consumer electronics companies, not device manufacturers, and I have had to persuade them that they do, in fact, make the devices in which I have been interested. ***************** GSI Musical Electronics 228 Washington Ave Belleville, NJ 07109 (201) 751-7505 (11-6, M-F) Tube related items, but I don't know much about their range of stuff. High voltage caps should be available. They are big on Dyna ST-70's. They supply a fair range of good tubes, I believe, and assorted amps and preamps of their own design. ***************** The Tweak Shop I don't have an address They cater to the fringe lunatics, with fancy cable, connectors, etc., in addition to good caps and resistors. I saw a catalog once. If you look carefully, you can probably find useful stuff from a builder's point of view. Pricey. There are other places like the Tweak Shop, and I expect others on the net know about them. They are all outside my price range, and I have not dealt with any of them. ***************** Douglas Kent Smith Consulting (or some such name). He provides high-quality tubes and assorted technical information on their use. I don't know any more. ***************** Audio Research Corporation Minneapolis, MN They are in the book, obviously. They will sell parts at not terrible prices, and are obviously a good source of parts for tube projects. I believe they will sell you anything except their output transformers and their analog-modules, whatever the hell those are. They sell noise selected tubes, matched pairs, and so on. ***************** Stereo Cost Cutters They bought out the entire Dynaco stock, and are the principal source of parts for them, including the output transfromer for the ST-70. However, since you can buy a used ST-70 for about the price of the transformers, I am not sure how good a deal they represent. Still, if you are into Dynaco, their supply of parts and manuals is invaluable. ***************** There are a few surplus places, which are worth exploring. Their stock is often odd, and very erratic, but I have picked up various valuable items for very little. Of course, when you include the junk I acquired, the average cost may or may not be a whole lot lower than usual : Star Tronics (I picked up single-deck Alps pots for $3.50 each) Occasionally they have good stuff, but it takes a lot of sorting. ****** BNF = Hi Tek Sales = a couple of other names Hi Tek Sales 119 Foster Street Peabody, MA 01961 800-832-2321 Every now and then they have a good selection of largish electrolytics. ****** All Electronics Corporation PO Box 567 Van Nuys, CA 91408 800-826-5432 for orders 818-904-0524 for other things Very useful source of electrolytics, hardware, relays. I have ordered many useful items from them. Much better S/N than usual for surplus places. ****** R&D Electronics (Also known as Electronics Surplus?) 1224 Prospect Avenue Cleveland, OH 44115 (216)621-1121 (800)642-1123 for orders Surplus parts, but much better organized than most surplus places. A fellow called Geoff (Jeff?) knows a great deal about their stock. I got Grayhill 2P3T rotary switches for $1.50 each, although these switches require rather a lot of torque. I also got Grayhill 2P6T switches for the same price. The 2P6T look good for selectors. They are pc-mount, with the terminals on one end so that they can be used on standard board patterns. ****** Elcon Sales 470 Clifton Avenue Clifton, NJ 07011 This appears to be a mom-and-pop manufacturing operation which makes capacitors for the defense industry, including polypropylenes. They maintain something called an "off-price line" or some such thing, which consists of caps which are out of spec in some trivial way, like being 21% off nominal value, which they sell for much less than list. For bypass use and other similar purposes this obviously does not matter. They have a strong tendency to use copper-clad steel leads, if you are concerned about that sort of thing. This is not really a surplus place. ****** Marlin P. Jones & Assoc. PO Box 12685 Lake Park, FL 33403 407-848-8236 Poor signal to noise, but they have some useful items. They have high voltage supplies which should interest ESL builders. Also, quite often, they have large electrolytics, useful for power supplies. ****** Herbach and Rademan 401 E. Erie Avenue Philadelphia, PA 19134 215-426-1708 Closer to a useful, general purpose surplus place than most, including some new stuff. They often have high voltage supplies and transformers which are quite useful. The transformers are quite ordinary in quality. Don't expect to find toroidal jobs. ****** Jameco Electronics 1355 Shoreway Road Belmont, CA 94002 415-592-8097 Surplus electronics. They have shifted progressively to digital products, but still have useful selections of IC's, etc. But the selection is rather odd. ***************** Dick Smith Electronics PO Box 468 Greenwood, IN 46142 800-872-1373 Various useful items, of variable quality. Good source for some kinds of hardware. Fairly useful. They want $2 for a catalogue. ***************** Marshall Electronics, Inc. PO Box 2027 Culver City, CA 90230 213-390-6608 Distributor of Neutrik and Mogami products. Good selection of connectors and cables Mogami 2830 is nice, flexible coax for internal wiring, if somewhat high in capacitance. Some distributors sell their products at a significant discount. ***************** Sescom, Inc. 2100 Ward Drive Henderson, NV 89015 702-565-3400 Enclosures of what seems to be good quality, but not the every best. ***************** Sunix, Inc. 3850 Steeles Ave. Woodbridge, Ontario L4L 4X6 Canada 416-856-2222 Reasonable range of enclosures with anodized aluminium front panels. Enclosures are available in steel and in aluminium. Construction is OK for preamps and similar things of limited weight. For heavier items, bracing is necessary. My power amp is in a Sunix enclosure, but I bolted a sheet of 1/8" aluminium to the base. Without that it flexed unacceptably with the transformers inside. But better enclosures cost a lot of money. A place called Strongbox advertizes high quality enclosures, starting at about $170 each. The ads appear from time time in Audio Amateur. ***************** Sonic Frontiers Inc. 181 Kenilworth Avenue. Toronto, Ontario Canada M4L 3S7 416-338-2562 Resistors, capacitors, pots, wire, connectors, etc. Looks promising. ***************** Avel-Lindberg Inc. 5 Old Town Park Road Unit 47 New Milford, CT 06776 203-354-8597 Excellent source of toroidal transformers. Their Cotswold line has lots of transformers which would work well in power amps. Good place. About $80 for a 500 VA transformer. I have used several Avel-Lindberg transformers over the years, and have been very happy with the quality, and with the service. Smaller transformers are somewhat expensive. All transformers have dual primaries. ***************** Amecon 1900 Chris Lane Anaheim, CA 91805 714-634-2220 Another excellent source of transformers. They have a possibly slightly wider range of higher VA rating transformers than Avel-Lindberg. I gather the quality is much the same. Most transformers, maybe all, have dual primaries. ***************** ILP Manufacturing Inc. 250 Wildcat Road Downsview, Ontario M3J 2N5 Canada 416-636-9418 I think Old Colony sells ILP's, by and large. OCSL prices are quite high, compared to Avel-Lindberg or Amecon, but I don't know if direct purchase from ILP or a distributor would be cheaper. As far as I know, the transformers have single primaries. ***************** American Design Components 201-941-5000 John Allen recommended this place to me. I have not done business with them yet, but may do so in the future. ***************** Parts Express 340 E. First St. Dayton, OH 45402 513-222-0173 800-338-0531 They sell loudspeaker drivers, hardware for loudspeakers, etc. I gather from a posting on the network, that they also sell Hitachi MOSFETS, although I gathered that these were slightly older devices. There are more recent versions, of higher current capacity, but I don't have details on what Parts Express offers. ***************** Sound Values Box 551TAA Dublin, OH 43017 614-889-2117 I believe these people are the current incarnation of Stereo Cost Cutters. They have the current supply of Dynaco parts, etc., and, inevitably, the usual range of tube-related parts. ***************** Mark V Electronics, Inc. 8019 E. Slausen Ave. Montebello, Ca 90640 213-999-6868 800-423-3483 (orders) They sell a range of kits for preamps and power amps. The kits are very inexpensive, and possibly too inexpensive to be of good quality. But it might be worthwhile to get a catalogue. They also sell power transformers (apparently no toroids), and enclosures. The enclosures may be promising, mostly for reasons of cost. ***************** Newtek Electronics 449 Howard Avenue Bridgeport, CT 06605 203-366-7575 Precision wound resistors, 1/2 W to 14 W, non-inductive. Custom values possible. ***************** F-Dyne Electronics Company, Inc. 203-367-6431 Contact Robert Furst at Extension 3 An apparently good range of good capacitors. ***************** Tanner Electronics 1301 W. Beltline Rd. #105 Carrollton, TX 75006 214-242-8702 Power transformers, including a toroid or two, some good op amps, including some Linear Technologies devices, computer grade capacitors (12,000 uF at 75 V for $3.95). The capacitors look very interesting. Inexpensive oscilloscope probes. (That information came from John Allen at ingr.com.) I gather that they have other interesting stuff as well. If they have tantalum caps at similarly attractive prices, I would be very happy indeed. ***************** Southeast Speaker Supply, Inc. PO Box 52-0637 Longwood, FL 32752 800-292-5559 for orders Grills, drivers, other parts ***************** Welborne Labs 6836 S. University Blvd. #70 Littleton, CO 80122 The usual range of builders' supplies, including switches, pots, resistors, capacitors, connectors, etc. They sell the Hitachi MOSFETS. $2 for a catalogue, applicable towards first purchase. ***************** Triode Electronics 2010 W. Roscoe St. Chicago, IL 60618 312-871-7459 John Allen, who posts occasionally, has ordered from them, and was happy. They have a large collection of tube related supplies, but also stuff useful to non-tube-ophiles. That includes enclosures, rub-on lettering (white, too, which I have been looking for), connectors, switches (at appealing prices), pots (ALPS at decent prices), output transformers (usable, backwards, for esl's, perhaps), resistors, capacitors, etc. I'l have to get a catalogue. ***************** Antique Electronic Supply 6221 S. Maple Avenue Tempe, AZ 85283 602-820-5411 Mostly tube related parts, but their list of output transformers includes the Triad S142A, which Sanders recommends for his ESL, so it makes it onto my list. ***************** From stevesaf@microsoft.com Mon Aug 9 18:01:24 1993 Newsgroups: rec.audio.high-end Path: stevesaf From: stevesaf@microsoft.com (Steve Safarik) Subject: Re: Where to get quality passive parts?
