My Hafler DH500 has one channel making popping and snapping sounds, worse on damp days.

Any suggestions on what to do or where to repair? Im currently in Europe so sending to the States would be the last choice.

Regards,

Noc

Make sure its not the speakers. You don't want to take the amp apart if its not faulty, very probable a bad solder connection in the amp itself. If not, then a scope is the quickest way of finding the problem component. If no oscilloscope available, try freeze spray and a hair dryer, it can be quick too. Focus on small transistors and capacitors.
