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 so much, auxinput. I'll let you know how we get on. I'll have to price out recapping the entire board and then make a decision, but I would love to. This is by far, the best sounding pre-amp I own. By which I mean transparent. I didn't even understand what that meant until I plugged this into my system.
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.
A local shop is doing the work. Not retail, just a repair shop fixing hi-fi and musical instruments, who are attached to a practice studio. They have done good work for me in the past, and I trust them.
