Glad you found it

First don't panic about fault conditions occurring in the wee hours.
Slight correction to that statement.....

Dont panic about fault conditions occuring after you have been working for too long !

I doubt there is a single person on this list who hasnt made an error due to tiredness or distraction.

I think my worst error was when I was repairing a turntable that had a faulty transformer. I was wiring in a temporary replacement when someone distracted me. When I continued I joined up the wrong wires and stuffed 240V mains straight into the PCB that was supposed to take 20V AC.

Not ALL the IC's exploded... some just blistered... but the turntable had to go to that great disco in the sky
