I have a Galaxian with retrace lines showing up, however, there is no brightness adjust on the flyback. I'm not sure where the adjustment is located. The remote board doesn't seem to function at all.

I had to mess with one of these today. I recapped it, and noticed it had a brightness pot on one of the daughter boards, just like a 4600 does. I replaced the brightness pot, and was able to get a really good (well... pretty good) picture.

It was kind of neat, because you could see Wells' evolution. The 4600 is a condensed version of this monitor, uses the same daughter board idea, but ditched the audio circuitry, the crazy convergence board, etc.

Yeah, those 4500's are crazy looking. They're nothing more than "hacked" TV chassis.....notice the entire block of control knobs that arn't even used.
