NAD 7250PE intermittent noise on one channel

[edwinh]

I just got an additional set of speakers and took my 7250PE out of the closet and hooked it up, using just the power amp section. It sounds great, except for regular intermittent noises in the left channel. It sounds like a kind of rushing sound. Before I dig into it, is there anything I should be specifically looking for?

Look for dry solder joints on larger transistors that have heatsink mounted to them and reflow as necessary

Look for dry older joints on larger transistors that have heatsink mounted to them and reflow as necessary

Thanks!
