Since I have replaced the 4 transistors in that B/C section of the board, I am suspicious about the 2 LED’s that don’t illuminate. I will check the soldering joints. TY
It's very rare for one of our LEDs just just randomly stop working. Maybe I've seen that 1-2 times in 20 years. Generally there would be some other issue that takes them out as part of the failure process.

Very happy to report that after replacing the 2 LED’s that weren’t glowing on the B/C area of the board, the voltages tested in spec and the preamp sounds brilliant again!! Thank you for all your help & patience!!
