Might be a problem in the convergence circuit. Probably nothing big, and also I've seen a lot of Zeniths with SLIGHT gemoetry problems from the factory. I don't think the engineers were too worried in the 60s about geometry, as long as the center of the tube (face shapes, etc) was OK. That's because there weren't any graphics or crawls at the bottom, etc., to draw attention to bad pincushion/slight keystoning, or bowing problems.

Exactly. I agree completely. I've seen many zenith's that could have had better pincushioning, especially on their portable. The little 15Y6C15 in particular is a very annoying set to watch on letter box scenes.

I did find a pincushion adjustment - I think it helped a lot. I'll grab my crosshatch/dot generator and set up the thing later today.
it's a neat little set and I'd like to have it going nice so I can watch color TV here - the 19 inch B&W I have doesn't cut it...

The worst pincushion I've seen is on some cheapo hybrid imports sold by Sears and Wards in the early 70s. That and the poor color makes them tough to watch. I recall trying to find an adjustment on one of them but never had any luck.
