Vintage Tube Amp

Up for sale, a 1967 Ace Tone Mighty-5 head and 1×12 cabinet, near-mint and fully serviced. Founded by legendary Japanese engineer Ikutaro Kakehashi, Ace Tone can be considered an early iteration of the Roland Corporation (also founded by Kakehashi), known for its amplifiers, keyboard and early synths/drum machines. This rare Japanese-made Mighty-5 features a dual-channel, dual-input design (Normal and Treble), with onboard spring Reverb and Tremolo. At the heart of this amp are a pair of 50HB26 power tubes, rated at 25 watts, resulting in fantastic headroom and a notably even-tempered clean response, even at higher volumes. Tonally, this amp falls firmly in the “American” camp, but a little more Valco and a little less Fender. Channel One is full and rich, with brighter, crisp tones at Channel Two (regardless of input), and the Treble/Bass EQ knobs have a broad sweep. The tremolo is very musical, thick and pulsating, and the Reverb adds a welcome touch of atmosphere. The Reverb circuit is also highly unique, with two small reverb tanks inside the chassis (one tank per channel) coupled to a Reverb Balance control and dedicated Volume for the effect. The circuit has been extensively recapped, with the original transformers present. The power transformer has taps for 100v (Japan) and 117v (USA) operation, with a discreet switch on the underside of the chassis to toggle between voltages. The chassis stamp is from the 27th week of 1967, the original wiring chart is intact, and the stock two-prong cable is present (a three-prong cable can be installed at no additional cost). The tube complement comprises all of the original matching Matsushita-branded valves, with a pair of 50HB26s power tubes and a preamp comprising three 12AX7s, a 6AV6, and a 6AQ8. The cabinet is loaded with one 12″ speaker and one 8″ tweeter, and both original alnico magnet Ace Tone-branded speakers are present. The 12 speaker has been reconed, while the tweeter retains its stock cone. Cosmetic touches include black tolex, with black grillcloth on the cabinet framed by white trim and accented by a large Ace Tone badge. There is only light wear on the tolex, and the brushed aluminum faceplate has pristine graphics, with all of the silver barrel knobs intact.

This is in great working condition. This guitar amp has two channels. All you need is the speakers you’d like to add in which are 2, 4, 12′s. This is a very strong type of amplifier head. This amp sounds like a Reveria and Fender amplifier to be frank with you. It’s a bit heavy too but will be wrapped up securely. It is light but has great tone and power.

Offered for sale are the vintage Sprague Bumble Bee Mylar capacitors as titled and pictured. Fully tested for both value drift and leakage. Detailed test results according to my Sencore LC75 Analyzer can be seen in the photos (in no particular order). This is a particularly nice group of caps that all measure within 10% of their rated tolerance, even though their original spec is 20%. Note: for those measuring caps with a DMM, my Fluke DMM shows these as being a few nF higher most in the. 040.043 range but I have displayed the LC75 results in this listing since it’s a calibrated purpose-built machine for analyzing capacitors to a high level of accuracy. This is just in full disclosure / for what it’s worth. The photos are of the actual capacitors you’ll receive. Please ask any questions before purchasing.

Up for sale here is this box of 5 NOS NIB vintage Sprague Black Beauty capacitors. The caps are all marked. 1 uf 600v, and test around. 1.115 uf, with very low leakage. They will work great at full voltage. Please see my pictures for details and test results. If you have any questions, please ask. I have more capacitors and other vintage electronics listed–feel free to take a look!

Pulled this from a 1960′s WURLITZER Model 420 Spectra-Tone Cabinet – like a Leslie with rotating speakers. Has 2 RCA 6550 Power Audio Tubes (one is bad, as shown).
