Default Re: Baird T5 restoration project.

Hi Andy,
There is three Cossor 15" CRTs upstairs and one in an English Electric 1550M TV set, the model with FM radio.
I've been reluctant to boost the tubes fearing that the cathode surfaces might be ruined completely.
Nothing to do with the T5 restoration but the preamplifier unit that was fitted in the T23 was found yesterday. The preamplifier was not made by Baird Television Ltd., but it is nicely made and was fitted on the right side cabinet panel. Uses a single Mazda SP41 pentode.
It begs the question should the preamplifier be refitted into the T23? After all it's part the set's history.
