b5oo second channel on the go...

apex...,,
sir..,,
tonight, i had a sigh of relief...i finally made my second channel work...:D:D:D:D:D:):):):)
i replaced all MJE340, MJE 350 and replaced zeber diode 15v...

but there is one thing i am concern...when amp is powered on and speakers tapped to output, dc voltage occure at output...but powering amp without the speakers, amp work normally...
what could be the prob???...:confused::confused::confused::confused:
tnx...
regards...
