Several years ago, I made the 'classic' mistake of either disconnecting or reconnecting the +ve and -ve leads from the PSU (Minicap6) (I can't recall which) BEFORE checking the PSU was fully discharged !!
CONSEQUENCE damaged board and DC off set measured about 150mV ! (possibly higher as I'm working from memory).
Now I've a little time on my hands I thought I'd try to repair them as they are currently useless, so I've nothing to lose.
Any suggestions of most likely blown components or where to begin ?
I dimly recall a previous thread on the subject, but despite various searches I can't find it.
