I posted previously about a volume imbalance in my 8ks.

George Meyer diagnosed some bad power supply caps and quoted about $1750 to replace all of them in both amps, around 29 in each.

Just got them back and hooked up, setup a dB meter and they’re measuring identical to before repairs, 5-10db difference between speakers. Adjusting the tweeter output in the service menu still doesn’t change the actual output.

Prior to the repair, they had a dead silent noise floor. Now when turned on, there is a very noticeable white noise/fuzz coming from both speakers.

I’ve already dropped them back off at George Meyer to give them a chance to make it right, but now I’m wary of what comes next.

And while I assumed there would be a significant markup on the capacitors, I see they’ve used Suncon and Wurth Electronik caps, probably $5 in caps total at retail price, that they upcharged to $700

Does anyone have a guess as to where the noise floor fuzz came from? Could it be the quality of the new capacitors?
