Anyone able to post photos of PTP boards from the original Marshall 20Wer?
I just picked up a '72 PA version and it's had some work done (e.g. changed to 220K mixer resistors) and seems to have the "other" PI arrangement (the PI variant that's drawn in on the schematic on p212 of the Doyle book).
I'd quite like to compare the circuit with other amps.
