@ Rutger, Glad to hear it worked out.
I just made a fluff up job of using a pre existing power amp board to run multiple opamps for a foldback I'm trying to get up and running on the cheap and forget to check the Zener regulation.
So now I have to pull the 1k resistors (need 330 R) off a small tight space and I've stuffed the cheap PCB tracks from the power amp circuit board.
So back to the bench to make a whole new board for the power amp and PSU,,,,which I should have done in the first place.
Serve me right for cheating too much.
and Thanks Roly
,, yep I hang my head in shame, should have known what E stood for.
I doubt I'll ever totally conquer the mountain but I pick up a lot from wonderful folks like you and I feel more confident to take on slightly harder stuff but I try not to get in too deep cause I know darn well I'll get caught out if I'm to cocky about it.
I say that as I take on another repair which erks me a bit,,I don't like PCB Valve gear much.
Can't even get the red knobs off the front on this Fender, broke the pot shaft on one already.
Surprising how little electronics is actually involved in repairs
as a lot seem to be more mechanical issues.
The leaky power caps where easy to fix but now it's turned into a major
headache that will take a lot longer to fix.
Such is life.
