Mylar caps are the last thing to pop, I did 1 in all the gear I've repaired. Try it, who knows at this point. Did you replace the diodes?
This what is known as discriminating tasteful pause...
Is the expression 'awaiting with ("Bated Breath?") the U.K. version of "baited breath"? or I suppose if you had a habit of eating bait while fishing "bait breath" could be used.
Putting out sound but still in protection? Or putting out sound out of protection?
do you have replacements for d601 d602 ? if so change them as it might be the cause of the problem .(AC leaking past them) it would rule it out anyway
also check c603 for orientation and continuity ..negative to ground . positive to r601 .
it wouldn't really explain loss of a channel though ..that looks like a separate issue as we disconnected stuff earlier so the protection should have clicked in regardless .
did you check the power supply board after the sparks ? if not it might be a good idea to check it over .
I don't have the zener diodes for d601 or d602. I can pick some up though.
c603 is a film capacitor.. I don't think polarity would be an issue..??
I started looking at F-2722, right-channel driver board. In checking TR702, I was seeing readings very different than those on the left board. Started poking around and have found R44 is open! Will replace R44 see what happens.
i wasn't referring to the zeners . ZD601 ZD602 i was referring to D601 D602 they are rectifier diodes .
