Re: HMV 1804 Television.
The attachment shows the waveform present at the anode of the KT61 frame output valve. Scope settings: timebase 5mS per division and Ch1 50V division.
A 100microsecond 30 volt P - P sawtooth drive is present at the control grid tag of the KT44 line output valve. The next task is supply 4 volts to the KT44 and find out if the line output stage is working.
