One knob is missing. Pots seem to move smooth. This was a barn find so it is dirty but I tried to clean it up some. I??m unsure if it??s ... view on ebay

Harmony Vintage late 1970s Guitar Amp AS IS for PARTS OR RESTORE
LOCAL PICKUP PREFERRED. Vintage harmony amplifier as is parts or restore. This was working. Circa 70s or 1979. I did date one of the pots inside the amp, and it shows as being 1979.
After years the speaker started sounding bad. I tried this with another speaker, and it was also not sounding good. During this process (06-2026) it stopped working.
I am not a tech. Not gonna get it fixed. Rather sold for

Very cool little dirt box! Sounds awesome. I have included a demo to show its sound. It works well. The tremolo is strong. Theres a little bit of hum at idle. Looks all original. The original jensen speaker rattles a bit on lower notes but is definitely over shadowed by distortion. It still has its original two prong power cable. This ships fully insured and packaged with care
