The real question is how does it look when viewing normal video? These older sets almost always look shockingly bad when viewing certain test patterns. It's just a fact of the limited technology available at the time. Old TVs are fun to restore, but don't expect to get the same picture quality as a modern set with a digital comb filter.

Forgot...the set does have a pin cushion adjustment. It's on the bottom of the chassis, so is it okay to adjust it while the set is on its side?
