Manufactured from the 1950s onwards, I think production was stopped around the mid 1970s, though I'm not 100% sure about that. Anyway, I've got the high voltage stuff sorted - I need to track down a few HV capacitors but that shouldn't be too difficult. What I need to do now is get the isolated 6V AC/DC - anyone got any ideas?
