16" RCA 6T74. The CRT shows 0.75ma after rejuvenation on my Beltron 2972E. It did have a brightener on it. After bringing it up on a variac I was able to get a horizontal line so at least the flyback is working. Cabinet is in really good condition but does have a few blemishes and scratches. The channel pointer is broken but usable. $25 and pickup only or I can deliver between St. Louis and Rolla, MO.
