Power cord upgrade from 2 prong to 3 prong, old cord included. Tubes: 5Y3, 6V6, 6V6, 12AX7, 12AX7, 6SH7(tremolo). Power Transformer: Tranco (867) #4670, Aug 1961.

Good condition and fully functional circa mid-1960s Harmony H400A tube amp made in the USA. 3 inputs and controls for on/volume and tone. This is a great option for both cleans and some broken up crunch when cranked up. Output I believe is 8 watts using 3 tubes that I understand to be original (35w4, 12au6 and 50c5) and 1 x 8 Jensen Special Design speaker (looks original). This runs with a slight hum and has the original 2-prong cord (use at your own risk, should be replaced with a modern 3-prong cord). I have tried to describe this as accurately as possible.

Vintage 1965 Harmony H303B “Widowmaker” amp in good working condition. Amp has been fully serviced with Nichicon capacitors, 3 prong power cable wired in correct polarity no shocks! , and a replacement Jensen speaker from 1999. Still has a full compliment of vintage tubes. This amp still has the original grill cloth and rear back panel and is in good shape. Shows some typical wear including snags and discoloration in the grill cloth, wear to the original tolex, and wear to the original leather handle, but overall well taken care of. Was used with a vintage Aloha pedal steel and wasn’t beat on or abused. No smoke or pet odors. Shows normal signs of use and wear for an amp of its age, but overall a really cool little amplifier that works great and has had the right work done to it to keep it running for the next few decades and to prevent any nasty shocks that earned it the Widowmaker namesake.

Up for sale, a 1967 Harmony model 525 tube amp in excellent condition and in perfect working order. Made in Chicago, USA by Valco (the parent company known for producing the Supro, National, and Airline brands among others), the 525 is essentially a Supro Thunderbolt with the added benefit of individual Treble and Bass controls. Rich, powerful, and nuanced, the 525 pushes 35 watts through a pair of original RCA 6L6GC power tubes and an original Jensen C15P speaker. For everything from rich cleans and wooly rhythm tones to saturated tube overdrive further up on the volume dial, this Harmony delivers a pure sound with a simple yet ingenious circuit. The signature sizzle, drive, and subtle compression of Valco/Supro’s preamp design offers a very dynamic and articulate signal balanced by the warmth and fullness of the single 15 speaker. The circuit is very original, with CTS pots that date to 1967 and original impressively sized transformers as well. The faceplate retains its original gleaming chrome plating, with all of the original black silkscreen graphics and lettering, as well as a minty trio of chrome insert knobs. The Jensen C15P speaker has a near mint black speaker frame, gold foil label on the ceramic magnet, and date code from’67. The original black ostrich tolex is extremely clean and the grill cloth retains its vivid red racing stripes. The Valco-made Harmony 525 is a classic, oft-overlooked model with the same preamp, tube and speaker compliment, and rich tone as the Supro Thunderbolt.
