This is a very rare new old stock valve, in its own box. Please note this is not a direct equivalent to TV4. This is the later version, launched in 1938, with a longer grid base and with minimum grid voltage of -18v not -5v.

It also functions at a lower line voltage of 200v and has blue tint on the upper end of the glass. It was longer lasting than the TV4. See pictures of test results - excellent. I welcome questions and can supply data sheets for most valves if requested.

I may be able to arrange other services if asked. If using the valve as an equivalent please ensure compatibility.
