1966 GE PortaColor Restoration

I think so. I at least know all the voltages to the tube match.

I may need to call in someone to verify for me on whether it's "proper" though, since I'm color blind.

How do I tell if the range is proper? Would a video help here?

A brief vid would help, showing what the color and tint controls are doing when rotated thru their full range, preferably including a pic containing flesh tone (since flesh tone is center reference for tint range). That brightness problem would be interesting to see also.

Okay, here's a showcase of where I am. Sorry for the long video, I was trying to capture everything that came to mind.

Highlights are:

The new video output tube seems to have cured the issues with those bright lines and the signal loss.

I'm noticing some odd behaviors on channel 8 and 9. 9 got better over time, but the static seems dramatically different on 8 from how it appears on the other channels. I showcase that in the video, but that may be normal.

There's a lot of noise in the picture even when I have a stable input signal. It appears to be a sort of cycling movement, scrolling up, and then scrolling to the side. I'll check a few more signal sources to see if that changes depending on the source, but someone else may recognize that issue.

As I already stated, the vertical wobbles when I lower the brightness, and the picture changes size.

There's audio buzz that I'm noticing, but that may also be a signal thing. It's not AC hum.

The color is off. I know the screen needs to be adjusted, but I'm noticing that the colors also seem to be out of alignment and following the cycling movements I mentioned before. I'm not sure if that's an alignment thing or a sign of a problem.

This isn't showcasing flesh tones yet. I'll need to grab a DVD player and set that up. I'll plan to tackle that this weekend. Right now I'm just focusing on picture stability and RF noise. I guess at this point I'm calling the picture "stable" but I feel like it could be better.
