Hi there. Newbie to this board. Just did a complete rebuild of my '70 champ and did some voltage readings before actually 'plugging in'. The only original part in the current build is the power transformer. I'm getting around 500v at the 5Y3 and Cap-can, around 475v at the 6V6 anode, and around 450v at 12AX7 anode. I'm using a cheap VOM so those readings could be off a bit. These are obviously WAY higher than what is printed on the schematics, and I'm a little scared to start using the amp. Are these normal voltages? Why the huge difference?
