Hi there some one has given us one of these units to look at, as it got blown up at a wedding party.
We took it apart to fing one 2sa1943 cracked , and one driver short on the left channel, we then replaced all the output devices, along with some resitors and two drivers. After checking all diodes etc we then powerd it on and when we try and align the dc offset and idle current, the dc offset on both channels jumps around from around -30 to +30, but the idle current stays at around 3.5mv measured from the test points. any advice ? |
