Eric, thanks for your offer.

I think the early 60s color GE model set I am looking for information on is the one (s) that uses convergence coils instead of permanent magnets.
I don't know just which GE color model that is.

It is thought by some, that these coils were the source of the "problem" with the GE color TVs.

It is not just the coils themselves or the connected devices to the coils, but the arrangement of those coils that were / are, thought to be critical to the nature of the "problem"

It is this coil arrangement, yoke arrangement, CRT and the connected devices that I have an interest in.

I hope some one knows which model(s) this is and could let me know.

Regards,

Newton
