RE: Hafler 9500 crackling in one channel

Opened up the Hafler this afternoon and cleaned the solder connections as best as I could. The board has seen better days, some connections were so close together I had to remove some excess solder and scrape the board where the connections may have been making intermittent contact. First attempt was a failure, screeching noise... Second attempt and all is good, no noise, dead quiet for the last few hours. But will leave it on for a few hours more and see how it goes. It looks like the amp was worked on too many times over the years and the board is not really in good condition, no loose tracers, though.
