Reese,
Got in late tonight. I will make changes tomorrow and work on steps 9 - 11.
But here are some photos of the area below the brown lytics and the pot.
On the pot...black wire goes to pin 6 on the rear 6k7.
The grey/green wire goes to the 6Q7 top cap, but has a .022uf/630V cap in the circuit.
On the 6Q7 side of the .022uf/630 cap, that cap lead has a 1.3Mohm resistor attached that goes to pin 8 of 6Q7which is jumped to pin 1 which is soldered to the ground tab
thanks again
martin
P.s. I think I've got some shorting in the pot as I can hear the brief crackle of arching going on at the pot about 5 sec after the unit is switched on. Originally the pot had a gummy feel when turned. So I did a real thorough deoxit washing. Was that some kind of ëlecrto-lube" that I washed out?
