Just found the same sort of thing going on with a small Arvin set I picked up from the convention, it had a brightner hanging off the CRT but it's nice and bright without it. Chassis was full of nasty capacitors, who knows what the original failure mode was that caused it to be installed.

Another interesting thing is the CRT had a cathode/G1 short that the sencore wasn't able to clear, so I hooked the tube to a microwave oven transformer and cranked up the variac till I heard a snap. Apparently it worked, the tube has great brightness and contrast.
