"17.1W is correct but there's a typo. It should read (440v - 39.8v)"
Yes, thank you. I fixed it.
I found a bad supply node resistor. It was a 10 ohm where a 1000 ohm should have been, and was distressed to the point it read 968 ohms in circuit, tricking me into thinking it was the 1K it was supposed to be. During unsoldering, one leg fell away. So now that it is corrected, and I have realized I forgot two things, A: this is class A operation so that whole 70% thing is not in play, and B: 6L6GC is 30 watts, not 25 watts. So now I am back to the original 470 ohm cathode resistor.
Here's where I'm at now.
Cathode resistor = 464 ohms
Plate voltage = 402.5 v
Cathode voltage = 31.6 v
6L6GC = 30 watts
This has this tube idling at 25.2.watts, and that is where I am going to leave it. Once again, trying to fix a problem in my own head only.
