Hi Andy,
I was forty-eight then!
Working my way through the T5 timebase circuits today. The line timebase circuit is almost identical to the T23 but the frame timebase differs considerably. The scanning coil assemblies of the two receivers will have to be compared, there is a distinct possibility the T5 scanning coil has four windings.
An additional electrolytic capacitor is connected to the frame scanning coil plug.
Also, the circuit around the Westector is more complex when compared with T23 which has the valve interlace diode.
