Hello all nice man, I trouble you little with problem hope understand not with face loss. Sorry due my very poor english quality. I beg not for embargo on me.
I happy to buy SANSUI 771 receiver. But the ampli has some trouble. So sorry for parent hard work money :tears:
I do this:-
A)Clean the indoor with compression air to go away dust many years treasure
B)Clean the pot, switch, connector, check fuse if not corret amp. Every thing said ok
C)Change the negative and positive rail capacitor for the power supply board
D)Change 1000uf capa at volatge regulator
E)Using with variac to slow build voltage and power on
So here it is now:-
A)Left channel sound is getting. Right channel not
B)DC ofset voltage left is minus 157 right is minus 220. When the Relay goes cut
Where to look for trouble maker? If change all capacitor in driver board and power board he will get over being sick?
