I have, thanks to Dennis & OTT, obtained a CRT tester suitable for testing early tubes as it has a heater transformer with tappings from 2V to 12.6 and not a current generator which, it seems, most more modern testers have for heater supply.
One problem is I have no information, operational or technical about it. Does anyone have such information? If so, I would love a scan or be able to borrow the information so that I can scan and clean it up.
It was made by Gruenther Instruments Ltd and has no model number. I can only assume that it is called "the Beamec".
