"I have three VT-4-C vacuum tubes. Does anyone have any specs on these?
Would they be good for coil work?
Basically the VT-4-C is the same as the 203A, a triode
rated for 50 watts nominal plate dissipation. Filament is 10 volts
at 3.25 amps, as I recall. Can look it up later. These tubes
should work pretty well for a low-power coil, provided they haven't
turned too gassy after all of these years; they are over 50 years
old and could be as much as 60+
