Re: Baird T5 restoration project.
Checked the values of the resistors and most are within the 10% tolerance range. Like the T23 the T5 timebase has hidden width and height pre-set controls. Connected the focus control to the timebase unit. Still unable to achieve full focus because the circuit has to be modified to suit the characteristics of the Cossor CRT.
The raster is deflected downwards because the 75,000 ohm standing current cancelling resistor has gone high value, it's connected to the third winding on the frame deflection unit.
The resistor will be replaced with two 150Kohm 2watt resistors.
