Restoring a "Rediffusion" set (possibly) - UK Vintage Radio Repair and Restoration Discussion Forum

I have a nice Philips Band 1 console set, from about 1953 from memory. Its a "Rediffusion" conversion with a knob on the back panel I think and probably a few mods inside. This, if I tackle it will be my first telly resto, (done dozens of radios etc), just want to know how a converted telly will differ from standard and how easy/diff to make it work via a standards converter?

Hello Steve,
That sounds more like a band 3 converter to receive ITV. If so it will be well worth while and a relatively easy restoration. It's probably based on the Philips 1100U chassis or its later version with a 14" tube. Nice solid sets and the tubes are usually 100%. Any pictures? Regards, John.

No, it doesnt have a turret tuner and the number 1200 U comes to mind.

It looks exactly like my projector set, but with a direct-view tube. Is there a 5-channel knob on the right-hand side?

Yes Steve, Its a 1100U/1200U. Great sets, fantastic pictures, Line output transformers never fail and they use a very reliable tube. Usually five channel via a row of plug in coils at the front of the I.F. unit. The I.F. frequency is 10mc/s and was usually converted to I.T.A. with a Philips unit or Brayhead. Well worth restoration. I have just been presented with an excellent example, a channel five model tuned to Wenvoe. Not sure how to tackle the tuning problem as the coils are fiddly. Channel can be identified on the top of the three colour coded coils. [under a magnifying glass!] Get that back off!
Regards, John.
