That's good.Ok so instead of answers I somehow have more questions.
- About the resistor in series, the previous tech didn't have the resistor's value, so instead he used two resistors in series to get the value. (150Ω according with the schematic).
Now, let's take those resistors in series out and measure them, and please report the values, I think those values are wrong That resistor seems to be R41 150Ω.
The bias problem I would bet is because the lack of 2SC984, although it will be wise to see what output transistors are installed.
VD1212 seems to be fine but they can become noisy.
Those are awesome fellows, Jim (R.I.P) was a contributor of this forum, but those kits are for F-2624 (9090DB/8080DB)
I can help you with the parts, just in case you want to order in mouser. ( Ithink I have a project saved there for 9090 or 8080 that I made for a fellow Aker)
Let me know if you have more question.
