Default Re: Baird T5 restoration project.

Hi Peter,
In my Baird T23 timebase chassis there is evidence of wiring that might well have been used for the 240/25 and 405/50 systems switching, although the wires definitely haven't been connected to anything. Something similar can be seen in the timebases of first generation EMI sets where the dual standard cableforms were still fitted in later 405 only receivers. In very early T5 models the preset controls would have been used to permit easy switching between the two transmission standards.
The preset controls are only accessible when the back cover is removed.
