"I have three VT-4-C vacuum tubes.  Does anyone have any specs on these?
Would they be good for coil work?

Raymond Koonce"

	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+
