PAS hum (full Curcio mod PAS)

I jumped terminals 1&9 and 2&9 and the hum disappeared. So I'm going to compare the wiring from the original manual to the volume, blend and rear jack board.

There is no loudness tap and I removed the loudness circuit entirely. Also I never hooked up the phono board after installing the power module. BUT it didn't hum before I removed the loudness tap and the phono board wasn't hookup up then.

Any other suggestions to follow while I'll poking around the manual?
