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

The Harmony PowerPal 4050A is a vintage plastic practice guitar amp is a rare and sought-after piece for guitar enthusiasts. This is being sold AS IS and not tested. The speaker looks ok and from what I can see the board looks ok. The side looks to have electrical tape on the sides possibly holding the casing together but I??m not certain. I did not remove it. 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 ... more

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

Here we have a neat Harmony H194 vintage tube amplifier! It features an art deco front with a woven grill and brown covering. It has an 8" speaker, volume control, tone control and dual inputs. The amp is in very good condition and good functioning order. The edges of the exterior show light wear and tear. There are other light signs of use and age too, but nothing too major. It has a modern 3-prong power cable and sounds really nice

Description: You are purchasing a Vintage Harmony 525 1x15 Tube Combo Amp. In good shape with bass & guitar capabilities. Sounds awesome with a guitar to my ears & runs without any issues, though it would likely benefit from a re-cap & tube replacement as it is a bit noisy & 60 years old. Original 15in. Jensen is in great shape. Certainly a sweet amp. Please inquire with any questions you may have prior to purchase ... more
