First, the 10V regulator failed a while back, now the amp faults and
displays "5V ERR."  I've not been successful in getting a complete
schematic.  If I can get the board number/name and schematic symbol (e.g.,
U1), I can fix this on my own as I did with the 10V reg repair. Requests to
the Elecraft help desk do get answered but it took over a month of very slow
communication. 

 

The list archives show comments about the 5V ERR fault, but no detail.  Any
assistance with a schematic symbol and board number would be very helpful,
especially if there's more than one 5V regulator in the KPA1500 amp.
