RE: 1960s Rediffusion Reditune TP48A

RE: 1960s Rediffusion Reditune TP48A

@cathovisor It is basic indeed and you may well be right and I'm thinking of it's use in a larger area than for what it is intended for. It would good to find some info on it somewhere.

RE: 1960s Rediffusion Reditune TP48A

@cathovisor I'm only guessing that the 3 pin din socket has audio out as well as in. The only way to know for sure would be to trace the wiring back or put a scope on there and look for audio as there...

Hard to believe that that machine is the same one that you started out with and that it actually works. Just shows what perseverance and determination can achieve. Anyway, I was going to say that the ...

RE: 1960s Rediffusion Reditune TP48A

From what I've been reading on the old newspaper archives it would seem that there would have been thousands of various Reditune machines out on rental in the 1960's and 1970's. An advert from 1961 st...

@katie-bush I do have an envelope with the address of Andrassy Gabor in Budapest. I bought something in 2019 (can't remember what). I don't suppose full address would help though.

Have you tried CPC? They show a range of flat belts. A longer flat belt could be cut and glued to size just to get machine going.

RE: 1974 HMV 2726 Coloumaster; Thorn 4000

@crustytv I think that replica vertical defleflection board is an excellent piece of work. Also just to mention that I do have quite a few pages of modifications that were recommended for the 4000 and...

RE: 1974 20" Ferguson 3C03; Thorn 4000 ; Super Rare

I don't know if you've read the section at the bottom right corner of the circuit diagram (part 2) it shows some of the mods that were done. If you were to do the mods it would save quite a few compon...
