Acquired a Muzak Amp, Model 1120. It looks like this:

If not built by Muzak...any ideas on who built amplifiers for them? It would be interesting to track down a schematic. Thank you.

It may have been built by McMartin.

Yup, McMartin. High quality amp. I was a bench tech at a Muzak franchise for a while, and know the equipment up to the early 80s well. :)

Gentlemen, thanks! McMartin 1120 Amplifier, here it is:

Same amp, different paint job. It might be close to a McMartin CM-35 or MA-20. Thank you.
