I want to build a push pull amp with the directly heated tetrode 2E25 operated in triode mode. My question is, should I connect the beam plates to the cathode?
Hytron 2E25, not 2E24. Looking at the datasheet, it does not appear internally connected., I assumed I would just connect one side of filament, but I wanted to be sure as I have never worked with a directly heated beam tetrode before.
Wait, what if I have a hum pot or center tap filament transformer and amp is cathode biased, would I connect to top of cathode cap?
