Thanks for the info regarding the "modern" in line CRT in my 1986 Zenith. I realize I'm about 30yrs behind the CRT technology curve. I still don't have a theoretical understanding of how the Trinitron works let alone the self-conversion yokes that possibly all current CRT TVs employ. Fink's "Television Engineering Handbook", First Edition of 1957 is my only professional reference source when I lost interest in TV as a hobby in about 1966. Now that I'm back into the hobby, I'll have to get the latest edition of Fink or its equivalent.....Tom
