I thought the Zenith 63-6444 control doesn't have the nylon mounting tabs necessary for isolating it from the chassis on many sets but the 63-7210 does. Seems the 63-9967 is insulated as well but I don't think the mounting material is as strong. Besides, my Sylvania requires one with a much higher range. My Electrohome uses the same crap focus pot design as the Sylvania but the resistance is very close to that of a Zenith 25DC56.
I've been looking on eBay for a sync separator IC. The Sylvania's chip crosses to the ECG820.
Japanese/Korean CRT size numbers are a little confusing to me, especially those on Sony CRTs. I often don't know if the number means viewable or actual size.
