Default Re: Baird T5 restoration project.

Work continues on the timebase chassis. Last night I discovered a selenium rectifier which I assume to be an interlace diode. It's most likely this component was fitted in 1947 along with all the other components that were replaced to return the set to full working order.
My Baird T23 also has an interlace diode. The component used for the purpose is a diode connected AC/HL triode or in my set a Mazda V914 double-diode.
Note the very vintage radio valve holder, looks like something from the 1920s.
