One trick to do to implement a "brightner" is to wrap an extra turn on the flyback for the heater. I think most RCAs of that era got the heater voltage off the flyback, usually 3 or so turns of wire. Of course, there isn't a whole lotta life left in that CRT, but you can squeeze a little more out of it.

Would a Beltron CRT restorer work on CRTs like these?
