Default Re: Pilot PT650 "Spacemaker" Television

I sorted out the HT rectifier tagstrip and wiring, connected up the makeshift mains dropper and switched on
I could hear the frame timebase purring away, but no line whistle. Measured the grid of the line output valve which was -35v so the line oscillator was working. Measured the boost volts- 500V so the output stage was at least doing something.
Rotated the line hold pot which brought the frequency within my hearing range, turned up the brightness and a raster appeared!!
That's all for now,
Cheers
Nick
