Perhaps a gun cleaning will freshen the CRT? after the brightners removed?
Sweet lookin set, I have 2 emersons an RCA and a sparton i hope to get to one day as soon as i master capacitor ordering and subbing.. Might have the ball based antenna you need.... have to check my tv piles... Meanwhile the 69 mach in the driveway is callin me for restoration as well..... BRAVO on the Admiral
