OK, this is a bit geeky, but I made a provision for a panel meeter in my case. I plan on installing a 100mA ammeter with a switch so I can switch back and forth between the two power tubes to check the idle current. Am I doing something dumb here?
Bigger question: Generally you add the ammeter in series with the cathode resistor on its way to ground, yes? Given that the cathode resistor is also allied with the filament supply (to float the filaments) where do I hook the thing up?
Thanks!
