ML No532 Amp Repair

Thanks all! Pyramid seems the go to for this fine amp!

I'm a long timer here at the Gon and reached out to Outpost4 b/c he came down to pick up a bunch of stuff from Pyramid. I now live in Austin so we hung out together and know each other from the boards. He's not a regular poster at the Gon but did me a favor and put up the preceding post, knowing that he had experience with Pyramid. 

Good luck!

Over the decades, I have had a boatload of stuff fixed by Chris Lewis at Pyramid Audio, including Levinson.  Pyramid is a Levinson factory service center.  I can’t recommend Pyramid Audio highly enough.

Thank you! Good to know! Yeah I definitely want a shop that knows this amp inside and out. Not a cheap amp to "practice" tech skills on. I really like the fact that the owner of Pyramid worked previously for the brand. That helps a lot!

Those service centers have the ML schematics and parts. Pyramid's owner, I believe, worked for the old Mark Levinson brand. Any one would be a far better choice than finding a repair center on your own.

When an amp causes a popping sound it's DC current going to the speakers. If it's preceded by smoke it's most likely a shorted output transistor causing nearby components to burn. Tracking down the problem without a schematic is very difficult.
