Thanks Mike and Jim! Now....More ?'s

Okay,

So last night I upped the bias from 50ma to 60ma in my amp. It could be my imagination, but I think it sounds better than before. My amp is a Cayin TA-30 35WPC ultralinear integrated amp. The curcuit is identical to Cayin's current production AT-50. I did a search to determine the plate voltage for this amp and came up with nothing. The stock amp is supplied with a quad of EL34's, but you can also use 6L6 and 6550/KT-88 types, as long as you adjust the bias accordingly. This amp uses very robust power and output transformers and it and the Gold Lions are showing no signs of strain at 60ma. Still, I wonder if you or anyone else here might know what the plate voltage rating is for these amps and what the optimal bias setting would be.
