I asked this question in at least two different threads, but haven't yet received an answer. Are dark-tint CRTs with aperture grilles and inline electron guns now the industry standard for CRT-based color televisions, or do some very cheaply made Japanese/Korean imports, with manufacturers' names we may never have heard of, still use the old delta-gun tube with a shadow mask? In particular, are there any late-model (1990 to present) Thomson-manufactured RCAs which still are still being made with the old style tube? I realize Sony has used the inline tube in its Trinitron TVs for at least 20 years, and still uses these CRTs in its new Wega sets; I'm just wondering, however, if other manufacturers have jumped on this bandwagon as well. Seems to me the inline tubes produce a much better picture than the original delta-gun tubes did. I would think the inline tubes would also be less trouble from a convergence standpoint.
BTW, where are the convergence adjustments in modern sets? My RCA CTC185A7 doesn't seem to have a conventional convergence board (as I noted when a technician had the back off the set for service a couple years ago). Are the convergence adjustments all in software these days? For that matter, are there any conventional potentiometer controls in today's TVs, or is everything controlled by adjustments in hidden service menus? I think the only standard control on my set is the focus adjustment, and even that is designed to be adjusted with a special hex-head tool. The master G2 adjustment might be directly above or below the focus pot, but I'm not sure. That's probably been incorporated in software as well.
