[NLRS] need heatsink and pass transistors for power supply

[Mark Brown]

HI
    Anyone have a heatsink that will hold 8 TO3 case transistors? The bigger
the better, I am building a power supply for my 48 volt 50mhz amp modules (I
am combining 2 modules, each one has 4 mrf150's driven by 4 mrf148's). I
figure I will be dissipating around 500 watts in the pass transistor array.
I am also in the market for some surplus transistors that can handle the
voltage, 2n3055's will work but are borderline voltage wise.
                                                Mark
