Hello all, i have a rci 2990 that was all done up by al at sparkys it can do 50 w dead key and swing 150 and was wondering how well this base would work with a klv 1000p with the svetlana tubes in it. I have a guy near by that has one he's looking to unload and i am thinking of getting it. Are these good boxes and what kind of real wattage will it do?
