For sale is an ECL80 / 6AB8 triode pentode audio amplifier valve / vacuum tube by Brimar, fully tested and working. The ECL80 was very common in 1950s and 60s black and white TV sets, where it either formed the audio output stage, or the frame output stage, or any number of various other uses. Found in some cheap record players too, nowadays, the ECL80 makes a great little headphone amplifier and is much under-rated as such!

This particular example has all original markings and is in good working condition, tested on Mullard High Speed Valve Tester at (80%+ on both pentode and triode - of nominal new emission).

A good chance to acquire a guaranteed, working device at a sensible price for a tested item. Of interest to set restorers, audio experimenters etc.

Normally I wouldn't list such common TV type valves, but several customers have asked me to provide a reliable supply of such tested items, so here goes. But I can't sell them for 99p, as to test and select good working items that are some 60 years old takes time, care, equipment and knowledge.

So why risk a 99p untested valve when you can get a "guaranteed working or your money back" one from Helmore & Hunt? Just see our excellent feedback!
