Took my Levinson amp in for repair

Mrmitch,the biggest difference between your experience and the original posters is that your vw was still under warranty. Huge difference.

Picked my amp up Friday
The two who poked around with it talked with me
I ask if they heard the noise in the left channel, yep when we plugged it in we could hear it, turned it off and tightened some screws on power supply noted leaky cap, put it back together turned it on started smoking, but no we didn't cause it

I have heard about a lot of ML 33x series going in for repair but very very few come out fixed.

"It had some noise in the left channel the dealer called today stating they pretty much blew it up and I need come pick it up
Is there anything I can do about this?"

Did the dealer actually use those exact words ? IMO, if you take an amp that has one or more bad caps to be repaired, and when the service tech powers it up, it starts smoking, that is part of the risk you take in having it repaired. The only way to verify operation and take measurements is to energize the amp, so the element of risk has to be taken for granted. It does not sound like the tech(s) set out to deliberately "blow up" the amp, so why expect the shop to pay compensation ?
