So I just got my bassman head project wired up and it has issues. I followed Rob Robs start up procedure using a light bulb limiter and things went well, until I plugged in a speaker and a guitar. With the channel one volume and the master volume (Frondelli) all the way up there is almost no speaker output. I swapped around tubes in the first 3 spots (all 12ax7) and still no volume. So I pulled out my trusty DVOM and I have some strange voltages. I wrote out a chart like Robs and compared voltages and here is what I found.
