Up for sale, a 1962 Vox AC-4 in exceptional, collector-grade condition and in perfect working order. This early JMI tube amplifier is 100% original and complete, with original fawn tolex, brass vents, stock transformers, and even the stock “woodie” footswitch! Powered by a single EL84, this amp delivers classic Class A Vox tube tone at bedroom volumes, with a tone that actually stays quite clean. With simple Volume and Tone controls, the circuit is a pure platform for highlighting the guitar plugged into it, with a dynamic sound that can vary notably based on the pickups that are pushing the original 8″ speaker. The tremolo is particularly fantastic on this amp, with a thick, warbling three-dimensional quality that belies the amp’s small stature. Still wired for the original 240V power, this Vox comes equipped with a step-up transformer to convert the voltage from US to UK power while maintaining the amp’s originality.
The circuit is untouched and point-to-point wired, with original transformers including the Richard Allan model 5200 output transformer. The original Mullard mustard capacitors have A2 date codes, indicating production in the first quarter of 1962, and the stock Elac 8C 8″ alnico speaker is also present with its original cone and a clean gray frame. The faceplate and underside of the chassis retain clean, original silkscreened text, and the original brown pointer knobs (with their often missing gold inserts) are intact. On the rear panel, the original metal Vox serial/model plate is intact and of the fifth iteration issued by Vox, with clean text and only light surface wear.
Overall, this is a very clean, complete, and early AC-4. The original fawn covering and brown diamond lattice grillcloth is intact and in great shape, with light wear on the bottom front edge of the cabinet, as well as light staining on the top of the amp on the left side, near the brass vent. Given the fragility of the grillcloth, the condition is actually quite remarkable, and the cloth has only one spot of wear along the top edge of the speaker cutout. The original rubber feet, brass vents, and molded black handle are all intact as well.
The original “woodie” tremolo footswitch is intact.
As mentioned above, this amp is still wired for 240V, and comes complete with a step-up transformer to convert the wall voltage to the needs of this AC-4.
