Runs without any issues, though it would likely benefit from a re-cap & maybe a tube replacement. It has a minor hum when on. Which sounds like a normal old tube amp hum. Has its Original 15in. Jensen is in great shape. This is a rare find. I acquitted this from estate of a professional musician in New Hampshire. You are welcome to pick this up here in Waldoboro, Maine.

Powers on with loud hum.

In pretty good condition.

Jensen Harmony H420 amplifier. Unknown working condition powers on speaker makes noise but needs thoroughly cleaned it’s been in storage for a long time.

You are looking at a Harmony H205 amplifier. The original 12 in Rola speaker ein code dates it as either August of 1953 or 1963. These first appeared in the 1950′s, so I’m guessing 1953. The overall condition of the amplifier is very good considering the age. There are small scuffs here and there and the grill is somewhat faded. When I bought it a few years ago, I had the cord changed to a three prong, replaced the handle and replaced some capacitors. It has been played in my studio since then. It has two 6V6 tubes and puts out 10 to 15watts. It has 2 guitar inputs and a microphone input or for third guitar. There are 2 volume controls and a tone control that also turns the amp on and off. There is some 60 cycle hum with higher volume which is common in these amps. The amp has a nice overdriven tone when cranked. There is a schematic stapled to the inside of the amp. This is your opportunity to get a cool vintage hand wired point to point amp made in Chicago, USA. I gladly answer any questions you may have and good luck.

Estate find, plays, might need new tubes or servicing as I’ve not done anything to it. See photos to view condition.
