All that was necessary was to have the UHF tuner fitted when BBC2 became available in your area. |

Re: Single Channel 405-line Receivers
Pre-war sets were London only, Ally Pally. Post war, London only sets came first, then Birmingham only sets. After that as new stations were brought on stream it's my belief that from that period onwards sets that could be tuned in to the new stations, Holme Moss etc, 'replaced' the dedicated single channel ones; they were tuneable. So I do not believe that their were single channel sets for any transmitters other than London and Birmingham. In my time as a collector of vintage TVs in the 70s and 80s I travelled all over the country to buy sets and I never came across one that was different to what I have just said. The Bush TV22 being an example of a set that could be tuned in.

Re: Single Channel 405-line Receivers
The Bush TV22 is fully tunable to receive all five BBC channels. The TV12 is a TRF receiver and was designed to receive one BBC channel only. A TRF "Birmingham" TV12 was made.
I understand that certain late production TV12 models were equipped with a five channel superhet receiver unit. Is that correct? DFWB. |

Re: Single Channel 405-line Receivers
I guess those old tin-plate cased, self powered, 2 valve, Band 3 adaptors that would perilously hang off the back of the set was the "set top box" of its day! Edward

Re: Single Channel 405-line Receivers
That sounds like the box we had Edward, only ours sat on top of the TV. It had a cream front panel and the casing was steel with hundreds of little holes in it. I think there were only two controls - on/off switch and an ITV/BBC switch. We kept it for a few years, after we had the new set, but I took it to bits when I became interested in electronics/radio.
Thanks to all. Aub

Re: Single Channel 405-line Receivers
For our first TV, a Bush, bought for the Coronation, channel selection was via a 2-pin plug link that could be inserted in any one of five positions, marked 1 to 5. Living in London, we never needed to change channels, and I only know this because after we had got a new set to receive ITV, dad gave the old one to our neighbour (a semi-retired rag and bone man), retaining some of the parts that lay around in the shed for some years after. I used to play with paxolin panels salvaged from the back, and remember the channel selection plug, as well as the voltage range plug, which had positions in 10V steps covering 200V to 250V AC, but only 230V to 250V DC.
