How much power did the driver tube put into the final tubes? Without the driver tube, maybe it needs more drive from the radio? My Context 500 amp has 1 driving 4 and does 200w dead key and only swings to about 375w and this is with a Stryker 440 that really swings and is turned down to about 5w. I can make it do 400w with no swing. I always hear people say 1:4 but I don't know what it takes to get it. I am interested to see if you have come up with a solution for this. I am definitely looking at changing the bias in mine.
