For sale am EL81 / 6CJ6  pentode line output / series regulator valve / vacuum tube by Mullard, new in original Mullard box, recently tested, no faults and working at 100% of nominal new emission.

The EL81 was the less common version of the much used 300mA heater chain version of the same valve, the PL81. These were primarily deigned for line output service in black & white TV sets, with the 6.3 volt EL81 more likely to be found in series stabiliser service in professional equipment. They also make a very good Class A audio output amplifier and even with a pair in push-pull (9 watts RMS out).

These particular examples are all brand new, unused (apart from recent testing) and are in pristine, clean condition with all original markings present and fully readable.

Reasonable prices are asked, as these vintage valves do not store themselves for 60+ years for free and neither do they test or list themselves, which requires equipment, knowledge and time!
