I noticed a slight buzz in a high end power amp that was isolated to the right side channel and doesn't increase when adding volume to source material. Roughly two months ago for the first time I heard this audible buzz. It went away after I powered down then back up, all seemed fine and quiet as usual. Until yesterday when I caught it for a second time several weeks later.
These amps have one of the quietest noise floors (madrigal design group Proceed amp2). This interference pest noise in the one side is not loud but it is apparent straight away with the volume lowered.
I'm a complete novice when it comes to repairing circuits, I can handle soldering but not much more than that. I'm able enough to slide the top off and inspect for a bulgy or leaky cap, things of that nature. Some guidance is appreciated.
Of the top do the symptoms sound like its something minor like that? I recall fifty send caps being the gremlins behind sporadic intermittent audible noise in amplifiers before. Since this is one of my very favorites I'll cross a couple fingers.
I'll track down the other schematics, I know they exist on the web in a pdf as I ran across those illusive pages before, saved in my previous laptop I no longer have.
