In other news, I fished out the 1952 Admiralty Advance tube audio frequency generator from storage and have dropped it in to my regular guy who services analog stuff for me, he had a good chuckle and said it was a nice change from the stuff he usually works on, said he last saw one of those when he was at college cira 1970s.
Anyhow, he's gonna give it a service and check over to make sure it's safe, maybe fix it if it is faults, as I couldn't get any sounds from it, also he's gonna put in a 1/4inch jack socket which will save on buggeration with the connector things you're meant to wrap a wire around.
