The list will be further updated as the site gets updated, and I use the original format (I try to keep the differences between this first list and the second one to a minimum) including heater voltages and currents as follows:
[valve no.] [category] [base] [heaterv] [heateri] [pinout] [Vanode] [V(g1)bias] [equivalents/usage].
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 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.
