Horz linearity is not the greatest on the far left, and also looks like there's some ringing on the left side of the screen. Can't really tell in these photos, but it's there. Books tell me look for issues in the damper circuit... which this set doesn't have much of one. There's no damper tube. It seems, instead, they use a 3000 ohm 20 watt resistor. The original resistor opened and someone installed another in the cage. Also, I was looking for 560 ohm resistors in the yoke, but this set doesn't have any of those, either.

I've changed just about everything in the horz section... there's not a lot left. In the diagram, it shows R64 and C52. Those two components are no where to be found. I'm going to try installing them as per the diagram to see what happens.

Something I've never noticed in other sets... this set uses the 6BQ6 for both the horz oscillator and output. Usually, those are separate tubes.

For the most part, the picture is decent. I've watched it for several hours with no issues. I was thinking it could be a little better, but being a bare-bones set, I might not be able to accomplish much more.

I am, however, interested in getting rid of the retrace lines. I recall it's just a matter of installing something like a .05 cap somewhere on one of the CRT grids. Can someone direct me where that should go? Is there more to it... or is it just a cap?
