Weird Sounds

[btol]

I've got an intermittent squeeing/clicking/buzz sound on the left channel. Lasts 1-3 seconds and happens every 15-30 minutes or so. It started as some crackling so I reflowed solder joints on the 8 terminals of each tube socket. That seemed to fix the issue for a couple days but now this new sound. Started when the Moreplay had been on for a few hours. Should I just go on with reflowing each solder joint until the noise goes away or should I be on the lookout for something else like component failure?

I would definitely be looking for a loose solder joint, but a clicking noise would also bring in the possibility that this is wireless interference from a nearby device.

I had a similar problem.  Moving the router, which was 3-4 ft away from my electronics, fixed the problem.
