How can a amp like the R30 run 4 tubes rated at 12 watts each at max which is about 48 watts only get 30watts ?

I do not have a oscilloscope too test , but I know the plate volts are 375-379 which is high as you want with these 6v6/el84 tubes.
You would have too put the tube mix control at noon too test it.
Maybe Bruce will read and reply , he knows full well since he designed it and set the specs.

Anybody run a test let me know , I found my bias drifted up over time and I red-plated a tube .

Those little trim bias pots need too be checked , I smoked a tube 3 times over 5.5 years since 2012 :aww:
 
Same goes for the Rebel 20 with its 4 - 12watt power tubes in push pull can get a bit over 40 watts ?
Any power test please reply with results whatever you get is good !
