Old Radios / Valves/Tubes data

Welcome to my main Old Radio and valve/tube data page. Last updated 17th December, 1999.

rec.antiques.radio+phono FAQ I have finally uploaded the FAQ for the newsgroup rec.antiques.radio+phono and although it is only my first revision of all the good contributors and editors in the past, I hope that it is at least helpful. The FAQ can be accessed under this link or by going to www.xs4all.nl/~tgale/oradio/index.html with your browser. Sorry it took so long to put up, but I have been busy with many things the last part of this year. There is still some information from Bill Turner and Mike Tobin which will be included in the FAQ before the end of December.

The list of valves itself follows later on; I have also included a few notes on substituting different valve types when the exact original is not available and you want to get a set working in the 'same way that a service engineer would have done then'.

The previous set of responses to enquiries can be found here but there's more coming. I am also going to include a lot more valve data, including that from e-mail enquiries, into the data below, in the next couple of weeks.

There is also a link to the very latest odd facts & figures which I have dug up in response to various Questions & Answers, click here to see the most recent exchanges. Since a considerable number of people have mailed me with requests of how to purchase various valve/tube components, and I have no commercial interest in dealing in such material, I thought I would place some links to businesses which *do* supply such stuff as and when I come across them. Well, there's a first one right under this link, which probably serves the U.K and close regions more than other locations in the world.

The list will be further updated as regularly as is practical, and I shall use the format (now including heater voltages and currents) as follows:

[valve no.] [category] [base] [heaterv] [heateri] [pinout] [Vanode] [V(g1)bias] [equivalents].

where:
[valve no.] is the main number of the valve (e.g. EL36)
[category] is the type of valve (e.g. AF, AF o/p, RF amp)
[base] is the base type (e.g. OCTAL)
[heaterv] is the heater voltage (e.g. 6.3V)
[heateri] is the heater current (e.g. 0.3A) *NEW* - not for all valves
[pinout] is the pinout (e.g. 1:g1 2:k 3:s 4:h 5:h 6:g2 8:g3 9:a)
[Vanode] is the rated anode voltage (e.g. 220V)
[V(g1)bias] is the control grid bias as quoted (e.g. -8.5V)
[equivalents] are a list of equivalent valve numbers (e.g. 6L21) or comments

The abbreviations used for electrodes are as follows:

   h    =  heater connection (indirectly heated)
   s    =  screening
   f    =  filament connection (directly heated, note where + or - quoted)
   met  =  metallising (o/s shielding)
   k    =  cathode
   g    =  grid
   a    =  anode
   bp   =  beam plates (as in a beam tetrode for example)
   ad'  =  anode, diode 1 (same as ad1)
   ad"  =  anode, diode 2 (same as ad2)
   g3/5 =  connection to both g3 and g5 (example)
   k/h  =  common cathode/heater connection (indirect heating)
   t    =  target (as in magic-eye tuning indicators)

* * *

Where an electrode is bonded out to more than one pin, then in general both (or more) pins concerned will be shown (e.g. 1:k 2:g1 3:k ...). When a pin is either not present or not connected, then it will not be listed (e.g. 2:h 3:g1 5:g2 ...). stands for Internal Connection, to which no other circuit connections should be made. TC stands for Top Cap. Directly-heated 'battery' types can be seen by the 'f+' and 'f-' connections for the filament rather than 'h' used for heaters of indirectly-heated types. The negative control-grid bias quoted is that for the main controlled electrode, in many cases g1, but sometimes g4 or so, as in the case of some hexode mixers, for example. DD stands for Double-Diode. A.C. voltages are RMS or rectified-output volts, not peak or P.I.V. A 'mix' description refers to a mixer valve, also known as a frequency-changer.

Some of the older type valve bases are shown in the following plate together with their pin numbers. These bases and numbers are as viewed from below (i.e. under-chassis side):-

So here comes the current valves list to date. *** TIP *** : using your browser's 'find' button, you could search for an equivalent valve number, since not all valves here are listed on their own. As the page is built up, more equivalents information will be added. Most of this is hand work with reference to my various books and notes, the only assistance is a program which I have written to speed up data entry, so please have patience!


If you have a query about a particular valve, within reason (i.e. no requests for hundreds of valves' data at a time) then mail me (address at bottom of the page) and I will try my best to find out data on the valve concerned. Include any information you already have, and allow at least a week or so for me to reply since I am often off-line for some while.

If you think of a better format for the list, please e-mail me with your suggestions. I have lots of data on both older and younger valves than these, and as soon as I can I will make updated issues of this page available. I am considering making the data pages available as a down-loadable ZIP file, and I'll let yuou know what I decide to do as quickly as possible.
