Building a Mojotone Princeton Reverb amp. All the way down to the testing. I've run into a big problem - I'm reading 833 volts at the power tubes. The rectifier is reading 328 volts just like it should. The diode board is correct with the proper polarity. I've looked over my wiring on the transformer section and everything looks good. I checked the eyelet board with the power tubes removed and every point I checked was reading about double what it should be. I'm experienced in soldering, having built tons of connectors, cables, rack panels, etc., but I'm a total novice at amp building. Anything of the top of anyone's head that I could check?
