I picture guys with strings of chokes, toroids and oil filled caps covering half the basement floor with 2000 volts on them. I tried one antec toroid transformer (the big one) then two in all sorts of combinations and they all sounded nasty or worse, with the DC through them. Gave up on that idea, they are a mess to mount, heavy and if you add some big chokes and an oil filled, its a huge amount of space taken up all with high voltage on them. I would rather use a good mod transformer designed for DC (like the RCA ones) or do screen modulation and have none of that mess. But there ARE those that think the more iron, the more glory. Piles of glory!
