View Full Version : 12QP4 worth Saving? wiseguy 07-01-2014, 05:48 AM I have a couple of CRT's that I have been saving but not sure if it's worth saving them. so is a 12QP4 worth saving for rebuilding someday? also a 19AP4 slow warming but was rebuilt once it looks. thanks! rca2000 07-01-2014, 09:00 AM Just about ANY vintage CRT is worth saving now--since NO ONE is rebuilding them right now Particularly old ones--like those. Slow warming--but still useable... Bill Cahill 07-01-2014, 10:13 AM Worth saving. Used in early Dumont, another brand I forgot, and, at least one Admiral which I have. Bill Cahill Tubejunke 07-01-2014, 08:23 PM I think that Crosley may have used the 19AP4. What about Zenith portholes? Didn't they do a run with them? bandersen 07-01-2014, 08:39 PM Sure, there are 19" portholes. Admiral, Dumont, RCA, Stromberg Carlson Zenith and other brands used the 19AP4. Tubejunke 07-01-2014, 09:45 PM Pretty good tubes for the first 45 years or so. Air city these days! Bill Cahill 07-02-2014, 10:30 AM Zenith didn't use the 12JP4. They used 12UP4, and, 12LP4.
