Hi all! I'm in the process of hand building my first amp, a modified PR clone, and have run into a possible issue that I'd appreciate some expert help with. I've been using StewMacs instructions just as a chassis wiring reference and have hit a discrepancy (I think) in the B+3 & B+4 wiring compared to Fender's schematic. S-M has the jumper connecting the plate load resistors skipping past the 56k phase inverter resistor, & then a separate jumper from that 56k resistor going to the B+3 connection at the eyelet where the can cap B+3 connects to the 18k resistor. This looks like it would put 320v at the PI plate load resistor instead of 240v as Fender's schematic shows. Am I not seeing this correctly, or is it an error in StewMac's instructions? Any help would be greatly appreciated! Thanks!
