For sale, Harmony H-400 guitar amp, chassis rebuilt, these amps were designed to run on line voltage, no power transformer, not the best design in my opinion, PT and hand wired board , installed see pics, OT and 8” Jensen speaker are original, tubes are 12AX7, EL84, solid state rectifier, fuses for mains and B+ voltage, speaker jack added so you can use external cab, volume control, and boost switch added with on-off and pilot lamp, original only had volume with on off internal switch , cab does show 60 years of wear, however it is solid, great recording amp, tons of distortion when turned up, will ship to 48 states and offer three day return policy, buyer pays return shipping.
