21cyp22A
i am confused about what tubes produce a proper red,i had read someplace last year that the 21fb22 was the one with a more reddish orange phospher,i had a ctc-9 that had a 21cyp22A and i looked at the red closly and thought that it had perfect red,while doing purity,i looked at my ctc-7 with a 21fp22 and of course it is perfect red also. (but much brighter than the 21cyp22) .and no i am not color blind!!
i have been searching for a 21cyp22 to install in my ctc-7 to make it original,but if the 21cyp22 version is really the one with poor red then i will just keep the 21fb22 installed..
