This is an interesting job that requires years of experience and knowledge. Such databases and options didn't exist in the past—yet technicians were still capable; today, even if you can find the database, the parts themselves are often unavailable.

I just did some work on a Yamaha DSP 1 that was 28 yrs old and still great.

I think it should show some reading in analogue multimeter in AC mode. I am not sure! Please take help of AI.
