Re: Baird T5 restoration project.
The sync separator works in a similar manner as the Plessey Mark 1 chassis. That is, the line sync pulses are taken from the anode of the valve and the frame sync from the screen grid. Initial observations of the frame sync circuit reveal the Baird or was it Bush designers had paid special attention to achieving good interlace. The T5 was considered a large screen set in it's time.
Unusual to find in a 405 line receiver with a double integrator to filter out the frame pulse train.
