Default Re: Baird T5 restoration project.

Hi Andy,
many thanks for doing a superb job, it looks great. As soon as it arrives I'll set about restoring the timebase unit. It's the only unit that hasn't been been fully checked over. The T23 can be employed as the test receiver, assuming of course the CRT can be made to work again.
The attachment shows the circuit diagram of the self-oscillating line timebase.
The line scanning coils are fitted on the CRT neck in the usual manner and the frame timebase employs that clever arrangement in which the oscillator transformer has those laminations which extend out to the neck of the CRT.
