I’ve been messing around, tweaking my latest build... https://www.tdpri.com/threads/super-lead-type-build-see-how-many-boxes-i-can-check.1059658/ I am using @robrob bias calculator page. Running the numbers, 50% max dissipation has me at 20ma. I connected my multimeter to ground and the cathode pin on one 6BQ5 and adjusted the bias knob until I hit 0.020vdc (=20ma). Multimeter still on and connected, I started playing a bit of guitar. Gain on both channels cranked, volume about half way up. Loud, crunchy, and glorious 70’s hard rock tones!! I look down at the multimeter display screen as I’m playing and see that it is now reading an average of 0.040vdc with spikes up to 0.050vdc on loud low full chords. 40ma ~ 98% max dissipation and 50ma ~ 123% max dissipation.!!! So, is “set it at 50% at idle and you are good to go” really good enough? Am I interpreting these observations correctly?
