I need some info on valves types 6AN7, 68H5, 6M5, 6V4 and 6BD7. I have one of each from an old radio I scrapped out for parts, and need more information like type, function, pinout etc. All I know is that they're 6 volt filament, miniature types. Not enough to be able to use them in any future projects.
Thanks, Dave NSW, Australia
