Hi there,
so I was reading the www.rectifierguide.com and saw, that the very early Rectos had different power transformers. They were changed form 561137 to 561140 somewhen in the transition from Rev F to Rev G.
At one time I had the chance to have a Rev C and Rev G to compare and I did check the bias reading as well as the plate voltage on both amps.
The Rec C had a slightly lower plate voltage around 420V whereas the Rev G had a reading of 450V.
So what do you think, are the different power transformers possibly provide different plate voltages?
