Questions about a CRT Brightener

[zeno]

A few more : Gently pry the socket off. If you just yank it odds
are it will tear the socket out of the CRT.
Brightener will boost to @ 8 VAC.
After the sets been run a few days try removing it. They do wake up CRT's
sometimes.
Rejuvenation only other choice. Can be risky.
BTW after @ 1980 a different type brightener was made & they dont
interchange !Those sets used 15,750 Cycles, the old ones 60 CPS.
