NARVA Glass envelope cristals suggestions
Hi everyone,
I have recently accquired some old glass envelope cristals, similar in shape to a tube, with a 7 pin base. Pins are gold plated. They are manufactured by NARVA. There are following frequencies printed on tubes: 108.630kHz 307.95kHz 556.04kHz 307.95kHz They look like they are in good condition with clear printings in yellow, but I have no possibility to test them. No boxes. If somebody has an idea what to do with them, or maybe wants to make any use of them please drop me a line. Thanks Lukas |
