Keeping up with the scary TV theme here's some pictures of the interior of the Baird T23. About the Baird T23. The set differs from other Baird TVs because the 15" Cathodevisor 15MW1 has been substituted by a Cossor type 65K. Same screen diameter but the latter is about 4 inches shorter. Other T23 sets have the same type of Cossor CRT so we know this is a factory conversion and the execution of the work was not done very well, at least that's how it was in my set.

My set does work in a fashion but the CRT has gone bad,
very bad. It's a lights out job the see the very dim picture. A suitable replacement is to hand, another Cossor 65K, however, it is a later type and has an ion trap gun assembly and is thus designated as the 65K/2.
It's possible that Cossor invented the ion trap gun?
The set was acquired in 1993 and was found to be in a terrible state. None of the modules were properly screwed into position and fact the set was stuffed full of newspapers to prevent everything inside the set moving about.
An easy set to get going but some of the practices of those times such as the fitment of those awful his-vis capacitors and PVC wiring will have to be addressed. Quite a lot of tidying up to be done.
The third attachment shows the compact vision TRF receiver. The sound unit is similar to the one installed in the T5 except it is modified for 41.5mc/s TRF operation. The 1936 T5 was a superhet receiver.
