After reading up about tubes like the 316A or 368A they leave me with a
few questions. Why are the filaments at such a low voltage with such a
high current? 1.15v at 4.5 amps is pretty odd. A few tenths of an ohm
contact resistance would really effect emission. The plate structures
inside look very small for their rated dissipation. The 368A plate looks
like 3 small fins radiating outward, really not much bigger than a 12AU7
plate. Its rated for 20 watts but does not say if thats continuous or
pulse operation. Does that sound right to anyone?
