Default Re: Ekco TC138 TV ( driving me nuts )

The Ekco TC138 is a development of the model TS88 so I assume the frame timebase circuit is the same.
Because the cathode current of the output valve flows through the scanning coils there will be a degree of picture shift. Excess current through the SP61 will a result of leaks in C20 or C21.
