Thanks Tony.
That's the only exception to the rule. There are some with one side of the
heater connected to the cathode. Only a few of these are made that I know of
Most either use the heater or a heated cathode element as the input. In the
case of the GS-35B, and a few others, it's different.
Just for reference, what are the different ones all can think of with the
heater connected to the indirect cathode?

Because the GS-35B has the cathode internally connected to one side of
the filament. 73, Tony W4ZT
