Silvertone 113/110.700

Update: got vertical, can stretch to fill phosphor if needed, wrong value resistor was to blame. I have too much horizontal with weird fold over and some retrace lines.

That looks to me like both sides of the picture are there but the horizontal output is not transitioning to the damper in a linear fashion. Have you tried another horizontal output and damper? What happens when you adjust the Horizontal Drive control?

I tried swapping the HOT + damper and it's the same. Horizontal Drive doesn't do anything.

Horizontal width doesn't do anything either FYI. those 24pf 3000v capacitors in series going between the fly and pin 5 on the HOT are original and one of the few things in the horizontal circuit I haven't checked......

Edit: Schematic calls for a 6BQ6 HOT, I have a 6DQ6 in there. Could this cause my problem?

6DQ6 is listed as a good sub, but never hurts to try what they originally used.

I swapped in a good Sylvania 6bq6gtb and a tung sol 6w4 damper and I have a better picture, the drive line isn’t as bad but pic is wavy and stretched to the left of it. Horizontal drive, width, and linearity do nothing still. I may take a break from the sweep and see why sound doesn’t work. It quit sometime during recap

Well we have a sudden shrink of picture for some reason. Horizontal lock is shaky. I checked for HV arcing, none of that. Changes the 1 Meg resistor on the hv anode, swapped in some other horizontal oscillator and sync separator tubes in for good measure. This guy is getting ready to get mothballed again
