Madrigal Proceed PAV Schematics

I have a Proceed PAV (the one with button volume control instead of knob) that I inherited from my uncle. I was using it just for 2 channel listening. It started shutting itself off intermittently when I adjusted the volume level. Now, when I power it on, all of the lights go on for a second, and then blank and then I hear a regular clicking sound. I assume that's a relay. Any advice on this issue would be appreciated.
But I am also looking to obtain the schematics or service manual for this component. Madrigal Labs is out of business, and I can't find any contact info for Madrigal/Mark Levinson on the Harman International website.

Wow, thanks again. I will pass this info along. Unfortunately, without the schematics and electrical signal paths and values, the tech says it would be expensive were he to engage in trial and error, and he couldn't guarantee success. I'm going to spend a few days tracking down leads, before I give up.
Sure, I could send it off to a fancy shop in Colorado or Seattle, but it's much more fun to do it hard (and cheaper) way.

Yeah, he is probably right.  It is most likely the capacitors that need to be replaced, but it could very well be something else.

IIRC I bought my PAV probably in the '80s.  It and a matching stereo amp replaced my Marantz 18 receiver.  Five of those amps, the PAV, and the 18 are sitting in a rack, unused for decades.  The PAV was replaced by a Cary Cinema for HT, then a Parasound JC 2 BP and Bryston SP3, and now an Ayre KX-5 Twenty and the SP3.  The Cinema and JC 2 BP are in boxes.  I've been remiss about not selling stuff.
