Good example of applied back bias and a good explanation as well. Also a perfect example of what the bored CBS era engineers could accomplish! So complicated. So stupid. I don't expect to ever see a reissue of that circuit.   :l2:
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Went Class C for efficiency
