Default Re: Baird T5 restoration project.

The Baird T5 project has restarted now that a number of important components have been found to enable completion of the electrical restoration.
The self oscillating frame timebase transformer has a winding which is employed to cancel out the anode current in the Cossor 41MP triode.
The 75Kohms high wattage carbon resistor in series with the balancer winding has gone high in value, up to 132Kohms. Two wire-wound 75K resistors were purchased from an online parts seller. The resistors will be reliable replacement for the original carbon resistors. The other resistor has been fitted in the T23.
