I never knew how important that cathode current was till I started working on my set and then was given the advice to make sure its ok , it was at 220 or 225 or something like that , I'd have to check my notes but it running like that was causing the fly to get hot after a while , now that I have it running at 200ma the fly doesn't get hot , I don't even think it gets warm , if it does its so low that it is tough to tell and is negligible , so get that bulb hooked up or even better the meter and make sure its not high , I was told I could probably take mine lower but the schematic shows 200 and the instructions say no higher then 210 , I didn't want to go to 180 as was suggested because the proportions are just barely right now , if it gets reduced anymore the only way a circle will still be a circle would be to adjust so theres is a gap at the top and the bottom and I don't want to do that.

is this cathode current issue important for the black and white sets too I wonder .
