Hi, I just started my jtm45 build using the valvestorm parts and instructions. Everything went fine until I got to the testing phase. With the preamp and rectifier tubes installed everything seems fine but as soon as I install the output tubes my fuse blows. I have already swapped a tube because one of them had a vacuum leak and I replaced a tube socket just to be sure that it doesn't cause the problem. Here are my voltage measurements without the output tubes and only preamp and rectifier installed. V1 Pin1 239V Pin3 1,9V Pin4/5 3,3V AC Pin6 234V Pin8 1,9V Pin9 3,3V AC V2 Pin1 205V Pin3 1,2V Pin4/5 3,3V AC PIN6 335V Pin7 205V Pin8 206V Pin9 3,3V AC V3 Pin1 275V Pin3 48V Pin4/5 3,3V AC Pin6 277V Pin8 48V Pin9 3,3V AC V4 Pin2 3,3V AC Pin3 491V Pin4 490V Pin5 - 54V Pin6 490V Pin7 3,3V AC V5 is identical to V4. Can someone help me figuring out what's wrong with my amp?
