14.5 kV of "picture power" on a big tube would not be very bright
I wonder what the Zenith's voltage is
as they were traditionally judged as having the best (brightest?) pictures
Checking back on my Tab Books color TV service manuals for the different makes from 1964-1975, I noticed the HIGHEST - 29 kV
was
in Zenith sets, specifically the 1973-75 CCII 25DC57, 25EC58 etc
PS Happy Birthday Sandy G, My Grandad's B-day was today he'd be 102 and probably on his 5th Zenith!
