Polytone Mini-Brute III Amp

Polytone Mini-Brute III Amp

I have sold this classic Polytone Mini-Brute III amplifier which I bought new some time around 1981. I'm leaving this page up in case any Polytone fans out there want to look it over.

It's a solid-state amp with one 15" speaker. Outside dimensions are 17"w x 18.5"h x 10"d. It weighs 30 pounds according to my cheap scale. It says 160 watts on the back; I assume that's power consumption and that the output power is less. I think I may have read that the output power is 100 watts, but I'm not sure about that.

A lot of people seem to be looking for schematics for this amp. I'm sorry to say I do not have any, nor do I know how to repair it. I was lucky enough that mine lasted 20 years without any problems at all! To all who are looking for help in this area: good luck!
