I found this photo on the Wigan Archives web site, I have cropped the photo to just include the TV but it is a photo of 3 adults, probably family watching TV. The article, snippet attached claims it to be circa 1946-1950. It could be from 1949 onwards as a few did receive BBC TV in this area from Sutton Coldfield, I understand pictures were poor. Holme Moss started in late 1951 and would not be surprised if the TV was tuned to that.

However if I can find the make/model and year introduced it could narrow the search. This is purely out of interest, if the archives are wildly wrong I will inform them.

Hi Frank,

Trawling round the web   http://www.thevalvepage.com/tvmanu/hmv/hmv.htm  my guess would be an HMV possibly an 1808 from 1949 hmm_gif

Thanks for that Marc, reading that web page I reckon its a 2808, that is a Midlands version for channel 4. I know there were some channel 4 sets around the Wigan area, 4 element band 1 aerials and reception was not that good. A friend of mine had one, I did not know him at the time but he has told be about it being the first in his area. I don't know what TV they had though.

Holme Moss starting in Oct 1951 made reception on a dipole a possibility, many sets in the Hindley area just just a dipole on channel 2 in the 1950's.

I will give the archive the information, do with it as they wish.

Thanks again.

Frank

Of course yes 2808 for the C4 version, wasn't thinking beyond the original London sets. doh_gif

Last night I sent an email to Wigan archives with a link to the valve page with the  advert for the 1808 and 2808 and the information on what the dates and transmitter that was probably in use. The advert also included the price.

I have just received a reply back from Alex, the man in charge of the archives expressing thanks for the updated information.

Console version of the infamous 1807.   Channel B1 sets were TRF and models made for other BBC channels were superhets.   The frequency changer valve was the Marconi-Osram X78, a miniature seven pin triode hexode, not enough pins for that type of valve so the heater and cathode shared a pin.   Interestingly, the intermediate frequencies were close to the 1954/55 BREMA figures being 35.00Mhz vision and 38.5Mhz sound.  

The X78 triode-hexode was possibly developed for the 2808:    http://www.radiomuseum.org/tubes/tube_x78.html

1808 London.    2808 Sutton Coldfield.  3808 Holme Moss.
