Hate to necro my own thread but I've passed on the CTC146 and now acquired a CTC166B from 1991, not in as nice of condition but free and local is nice. The picture looks pretty horrible though, and the controls for adjusting the picture are annoying. Is this a problematic chassis or just wildly out of adjustment?
