I started to do the same thing and it's not easy, at my day job i build rf amps and can get my hands on just about any parts "2907's, 2222's,etc" and have the help of there main tech, it was very hard to find anything that could handle that kind of load, with out big $$$$. if u find a cheap simple way to adjust 24 volt 10 amp I would love to know.
