Broken Mitsubishi DA-A15DC

[cjs27410]

My Mitsubishi amp DA –A15DC- stopped working last week. I purchased it in ’78 and this is the first trouble I’ve had.
After about an hour or so at 30-35% volume the left channel made a scratchy noise and both speakers stopped working. The entire left side does not warm up now. I removed the lower screen but I don’t see any fuses.
Is this amp worth fixing and can anyone recommend a repair shop? I’m in Greensboro but I can UPS it anywhere.
Thanks for the help.

Could be any number of components that failed. Any smoke or odor of overheated components?

See my recent thread. Sounds similiar. If you don't want it, send it to me.

I've kind of grown an attachment to the entire rack set up.

I can fix it in Nashville. Typically there is a zener in the diff amp stage that opens, so the diff amp no longer works. I replace both channels even when one is bad. My address and stuff are in my profile. When you ship, put the amp in a double box so the heat sinks are supported. They are not as strong at the bottom as they look.
