Re: Baird T5 restoration project.
Hello Jac,
the 15MW4 CRT has a 42mm neck and the Cossor CRT in the T23 it is 34mm. Both tubes operate on 5KV EHT.
Going forward in time, the 110* CRTs introduced in 1958 the neck diameter was reduced to 28.5mm from 38mm in earlier 70 and 90* tubes.
Measures to reduce the scanning power required by wide deflection angles.
The scanning angle in the Cathodevisor tube must be only 30 degrees or so.
