21fbp22 red gun advice

[timmy]

hey all i have this silvertone roundie with a weak red gun and the brightness is limited to the red gun to match the other colors. so what would be the best route to go to try to get more from this weak red gun, run the red gun on the crt tester for a few hours and see if it comes up but using the set didnt get results from that, or should i try to rejev the gun , or i have a single gun brightener for the red, which way would anyone think is best to go at this point. and with a weak gun and the other drives low to match up with the bad gun would this effect the contrast in a way that one way its soft and the other way things seem to take on black and get really dark, and the pic gets really lousy. i do remember the cutoff on the red gun was not good.
