Re: Supersonic Heterodyne radio 1920's.
Back in the workshop this morning , switched the set on , audio stages ok all voltages correct ,then I happened to touch one of the rf valves ,after a few crackles we have stations again, what had happened the valve had actually climbed out of it's socket ,
A bit of doctoring to the pins cured the problem .I am now experimenting with some aerial coils ,more pictures to follow , I need to retrieve the cabinet from the loft . Mick.
