Just replaced the output transformer and have come up with some things that I could use help with that I hope someone here might be able to answer ... 1) What is the acceptable line voltage spec for this amp? ( especially the high end) 2) What should the bias voltage be thru D1/R36 IN STANDBY? 3) Is the fuse a Slo-Blo? I ask these questions because the line voltage in my home is between 125 and 126. This puts my V4/V5 plate voltages at 492 and the V4/V5 grid voltages at 488. This troubles me in particular because I'm very close to the voltage rating of the 40/40/40 tricap (500). I have no Variac to lower my line voltage to a more reasonable 120 to see what those, and other critical bias voltages, would be. I figure the power transformer has a 1:6.2 ratio, so if line were 5 volts lower, I might reduce these voltages by about 30? By the way, my filament voltage is at 7. The bias voltage is at about -53, but when I go into STANDBY, it goes to -80 ... is that okay by design? Again, this is with the 125 line. All other bias voltages are reduced by about 60%. The amp sounds fine otherwise, but I don't have a trained ear really. Can anybody help?
