Default Re: Baird T5 restoration project.

Hi Peter,
Those controls are presets for the line and frame timebase frequencies and picture height adjustment.
It's possible that very early production timebase units would have a 240/405 switch and that's the reason for those blanking plugs on the control panel.
The first attachment shows the control panel of the Baird T5. The circuit diagram is of the frame timebase in the T23. A Mazda AC/HL is used as the interlace diode.
