I have a fixed bias push pull output stage in an amplifier, it has 2 6P3S-E's (6L6). Plate voltage is 324. I have a 1ohm resistor between the cathodes and ground. I've measured the voltage drop across the 1ohm resistor and get a result of 0.252v.

My understanding is that this reading should translate to the same number in ma.

I understand I need to multiply the plate voltage by the 0.252ma.

324 x .252 = 81.64

Do I need to do anything with that result or does that mean my tubes are dissipating 81w? 🤔 and if so, is that averaged out between both tubes?
