I just finished a Princeton Reverb clone and wondered if anyone has any ideas about next steps regarding the following... I plugged the power cord in to a home-made limiter (light bulb) and it lit up when I switched on the power. I checked several other working amps and none of them lit up. However when I went ahead and plugged in a guitar (still through the limiter), it sounded pretty good. All the pots were responsive, plus the reverb and tremolo worked fine. I went through and triple-checked the circuit and hit all the solder points again. The tubes are all pretty new, but I still plan on swapping each out one at a time. As for voltages, I only really checked the plate voltage at pin 3, which came up at around 300v, which seems low. I wasn't sure if this was because of the limiter, and I didn't want to plug it straight into the wall outlet until I got clear what is going on or if it's even safe at this point. Any thoughts on how to proceed? Thanks!
