That's one of the F words I was saying. I kept hoping for an epiphany to point out some glaring obvious flaw, and when I finally got it I just shook my head and laugh/cried for a second.

Thanks for the method. I'll employ that when I build my 183 :)
IMO the most difficult problems to diagnose over the internet are?

"The amp has a hum" or "The amp sounds harsh?"
Could be something obvious (in your case) or something not so obvious (layout,grounds,magnetic coupling)

These sort of problems can be difficult enough to find with the amp in front of you!

Glad you figured it out

Enjoy

Amazing work Prof!
Just saw this thread and went through every single message :) your hum-hunt was better than Netflix tonight, glad you got it resolve!
Also, thanks for the feedback on the board, I corrected the typos in the new revision. If you guys have any other comment or things that can be improved in the layout/schematic/board just let me know, your feedback is like gold!
Cheers from London,
