Zenith C1415U (16C20) Restoration

[jmetal88]

So, I'm very happy to say, after years of owning this TV set and not really doing anything with it, I have finally re-capped it and got it working. So I'm starting this thread to try troubleshooting a few more issues with the set.

The first thing I'm wondering about is the video signal. I've spliced in a composite video signal directly to the video output tube. The TV actually displays a very clear picture from this, but I've noticed areas of sharp contrast seem to 'smear' to the right-hand side of the picture tube. Do you think it would fix the problem if I implemented a video input stage like the one mentioned here?

The only thing I'm worried about is the video output tube looks like it's supposed to take a 1V peak-to-peak signal, and that stage is supposed to put out 3V, it looks like. I guess I could modify it to be unity gain, though I'd have to research the topology a bit more, first. What do you guys think? Or would it work fine like it is, if I just turned down the brightness?
