Hey Pat! Thank for the reply! Funny you mentioned that because about 30 minutes ago, I was actually comparing the Randall schematic which is a bit sketchy as far as signal path in some areas...at least for me. The way it's drawn, they often use a lettered legend method so one has to kind of...

Hello all, I figured I'd try posting here to see if anyone may be able to shed some light on this problem. About 2 weeks ago, I warmed up the amp on standby for about 7 minutes, and then, when I switched to full power, one of the 1.5k resistors on one of th power tubes cooked. I quickly...

Hello, The preamp tubes are 12AX7s and the phase inverter is a 12AT7. Output tubes are 6L6s. Go for JJs. It'll warm up the amp significantly. As well, if I'm not mistaken, the 4558 Op Amp inside, is part of the reverb circuit. The speaker, G12H100 Celestion should be the stock speaker...
