Question about blue lateral magnet and purity rings.

[bgadow]

I'm not familiar with the -68, but I think those used by RCA (and others) were fairly universal. I had a -31 with a bad one and used a one-size fits all from Oneida or somebody like that-had a long list on the back of models it fit.

There were several different designs of purity/blue lateral magnets but I have not had any trouble interchanging them between any rectangular delta gun set.

The convergence/deflection yoke housings are physically very similar between the CTC-68 and 31, however I think the impedence of the coils would be different enough between the tube type and solid state sets to make them not electrically interchangeble.

Thanks guys for your info on this. They are both deltas so I'll go ahead and swap them. As for the deflection coil housing, i wasn't referring to the yoke itself, but to the plastic shroud that it sits inside. (some models have the convergence board fastened to the top of this, others have it fastened to the back of this.)
