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

The LEDs are sensitive to excessive heat, so you could try replacing them for the sake of thoroughness.

I will. The two on that section of the board don’t glow. Could they possibly be the cause of my issue?

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.

Paul -
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!!
