For sale an HP210 pentode RF/IF battery valve / vacuum tube by Tungsram, new in original box and recently fully tested and working at 100% of nominal new emission. In pristine, new, clean condition with original markings present and fully readable.

The HP210 was one of the earliest RF/IF pentodes for use in battery powered receivers and dates from 1934. This would have been powered by a 2 volt LT accumulator for the filament and an expensive dry battery pack for the HT supply. This was commonly required when a property had no mains electricity supply. It was not really intended that radios using these valves were in any way portable!

A sensible price for this new, guaranteed, fully working, tested example of an interesting old valve/tube. Of particular interest to vintage radio set restorers, experimenters and collectors alike! This old valve / tube could make somebody's old 1930 radio very happy!

Why waste 99p on an untested valve when you can by guaranteed, working (or your money back) ones from Helmore & Hunt?
