Holy makrel!
That's over 10 watts. Try pulling the damper, and then the rest of the tubes one at a time, starting with the audio output, while watching the voltage across R127B. If the voltage stays up, it'll prove there's not a tube overconducting.
To save brutalizing R127B while troubleshooting, you could sub it with a couple of 100 ohm 10 watt resistors in series if you happen to have such.
