V18A pin 4 should be mostly DC, with most of the pulses filtered out, so that's OK. When the horizontal is out of sync, you would expect to see a beat note in this filtered discriminator voltage.

The 6AL5 must be wired correctly, or the horizontal wouldn't sync, so SAMS is wrong.

It's troublesome that the width and lin coils have no effect. Maybe you should check if either of them are open or if the connection to pin 5 or 6 of the flyback is open.
