Item Description
Listed 10 months ago
The AC50 was developed specifically for the Beatles so fans could hear them better live. The two EL34s produce around 50 watts. Both channels feature the "Top Boost" circuit. This is the Mark III version introduced in 1965 when Vox changed from a tube rectifier to a solid state rectifier. The power tubes are EL34 (2), 12AU7 (1), and 12AX7 (3).
This 1965 AC50 has original transformers, Tolex, grill cloth, knobs, handle, pots, and just a few replaced caps and resistors. It has been updated to more modern standards with the addition of a 1/4 inch speaker jack and a grounded 3 prong plug with an XLR connector. All preamp tubes are vintage Mullard and Brimar. The unlabeled EL34s appear to be vintage as well.
A few condition issues to note. On the Normal channel, the input closest the the front works and sounds fantastic. The input closest to the back makes noise but is not working properly. On the Brilliant channel, the input closest to the front makes noise but is not working properly. The input closest to the back works and sounds like it should.
With any vintage tube amp, it is highly advisable to get it serviced for safety and reliability as the electrical component values have likely drifted outside of specification over time. Therefore, the amp may not perform as it should and the chance of damage to critical components is increased.
