Hey all. Took the plunge and got myself a multimeter today to bias my amp. I've read here and elsewhere that these come from Fender biased cold, and read 34.5 mV. Turned the bias pot to read 40 on the nose per spec (about 1 o'clock on the blue bias pot). Is there any good reason to run this hotter, or colder than that? I've got the stock GT 6v6 R's back in there (4's in their rating system), after running old, fatigued RCA grey glass/black plates for a while in there that started to lose their lustre (just out of curiosity, I popped those back in there, and with the bias turned up all the way, couldn't bring them up past 23 mV). Any advice, please let me know (besides don't shock yourself; yeah, yeah, kept my left hand behind my back the whole time). Thanks!
