Vintage Tube Amp

Up for sale, a 1964 Vox AC50/4 Mk III vintage tube amp head in excellent condition and in perfect working order, freshly serviced with an extremely original circuit. This UK-made JMI AC50 is a real powerhouse, and the dual EL34 design has plenty of British sizzle and chime, with big, bold overdrive when diming it out, and tight, punchy low end thanks to the diode rectification. The amp pairs exceedingly well with all manner of guitars for iconic British Invasion-worthy tonalities. The circuit is extremely original and freshly serviced by our techs here at Mike & Mike’s Guitar Bar. All of the original transformers are intact, along with all of the original pots, and a preamp that retains virtually all of the original signal caps and resistors with Mullard mustard caps that date to the 3rd quarter of’64. There are two larger capacitors in the power supply to ensure optimal functionality, and the power cable has been upgraded to a modern three-prong variety. The tube complement includes a pair of Ruby EL34 power tubes, with a few original UK-made Mullards in the preamp. The head cabinet retains the original black basketweave tolex paired with the original lattice diamond grillcloth and white piping. The pack panel features dual multi-pin jacks and 8/16 ohm functionality, and adaptor cabling is included to convert the outputs to conventional 1/4 jacks. The blue/gray faceplate retains all of the original chicken head knobs, and other small yet meaningful original parts include the original plastic handle, raised Vox logo, one-pin corners, and model/serial number badge on the back.
