For sale, a superb performance output transformer-less (OTL) valve headphone amplifier.

Designed by Helmut Becker, it uses 4 off PCL805 valves. This is the forerunner to the AudioValve RKV headphone amplifiers, mega expensive.

Ideally suited to high impedance headphones where the headroom is massive, will drive headphones from 32 ohms upwards with aplomb.

Fitted with a bucking transformer internally so true 240V operation. 6.3mm output jack with 3.5mm adapter.
