It seems pertinent that the one adjustment that gave me a barely discernible image was the horizontal hold--and it had to be close to full rotation in one direction or the other.
Coincidentally I was checking C37 this morning. Couldn't get a reading without taking it out of the circuit and was reluctant to desolder it. But I will tonight.
I also located all the coil screw thingies (you call them slugs) and noted which sections they worked with.
I'll look over the Rider 19A1 manual and see what I can figure out.
Thanks,
Winky
