For sale a now rare PCF802 (9JW8 equivalent in USA) triode pentode valve / vacuum tube, generic type new in white box. The PCF802 is an interesting valve as it was specifically designed or timebase generation in 1960s / 70s television sets. The pentode acts as the master line frequency oscillator and the triode is a reactance (or frequency controlling) valve. These valves are not much found these days, so this is an ideal purchase if you have a vintage TV set that uses one.

This particular example is brand new in original white box and each has been recently fully tested on my Mullard High Speed Valve Tester showing no faults and 100% of nominal new emission on both sections.

A reasonable price for an ideal chance to acquire a now rare valve / tube in guaranteed working condition. Ideal for TV set restorers, experimenters and collectors alike.

Normally I wouldn't list such common TV type valves, but several customers have asked me to make available a good, reliable and tested / guaranteed supply of such valves / tubes. However, I am unable to sell them for 99p as selecting and testing them does take time, equipment and experience.

Why waste your money (and the postage) on 99p untested valves / tubes when you can buy "guaranteed working or your money back" working ones from Helmore & Hunt?!
