mosfet mod for old style 148gtl

yep the good news I sniffed the rm mosfet amps and they range
510-580's so it ain't no secret no more I updated the sitnger board with these IRF510's RS 1.99 :) and drive it with 3 swinging 35 to get 120 watts AM :) and can now volt it at 15 volts with out a heat problem :)

but the bigger the number the hotter they get..
so going to try out 10 IRF520's in line to get 500-600 watts am :)
right now trying out 16 IRF510's in line with a 60volt 100amp bridge
4 caps and a nice transformer :) all pretty cheap :)
this = 500+ watts at 90-100amp draw
 
Well, If it was me , I would just buy a little amp. Why take the chance on a great radio and screwing with something that is working for you.

But, everyones different that what makes the world go 'round.
