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 ...).
Some of the
So here comes the current valves list to date.
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.
You can E-mail the author of these pages
(Trevor Gale) by using this link.
on the Dutch Internet service provider XS4ALL.
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.
