I have a new JTM 45 build I am debugging. The unit works, but is lacking headroom. Distorts very quickly and kind of sounds cool at low volumes but my tweed deluxe clone is louder. I know this isn't right. I have a list of voltages, using KT66 tubes:
1 2 3 4 5 6 7 8
V1 220V 1.7V 222V 1.7V
V2 186V 1.1V 328V 187V
V3 248V 43V 251V 43v
V4 453V 444V -44V 442V
V5 455V 444V -45V 442V
It appears my plate voltages are consistently higher than what I've found on the voltage charts online. Also my heaters appear to be 5.8V AC, so slightly lower than the 6.3V I was expecting. Thanks for any help in sorting through this!
