Very nice job. I recently had a tricky 'Auto Picture Control' fault. Basically there was excessive IF gain. But if I turned the RF sensitivity control down far enough to get the right contrast, then there was not enough RF gain and noise appeared on the picture. Voltages and component values were ok. I only found the fault by scoping the line pulse feeding the APC circuit from the little transformer which in turn is fed from the LOPT. It was way down in amplitude and weird in shape. The little pulse shaping cap on the small transformer was faulty (the type that looks like a half watt resistor). I don't know who makes them, but I've had problems with them before when fitted as IF de-couplers.
