Hafler 9500 crackling in one channel

Recently purchased a Hafler 9500 Transnova. Works just fine, nice sounding amp. But one channel has an intermittent crackling noise, happens for just 10-20 seconds every few hours or sometimes not at all for several hours. The transistors were recently replaced before I bought it.

Any ideas as to where to start? Possible cold solder joint? Resistor?
