 JE> Ever heard of 'over-kill', Chuck?
 JE> A 20amp power supply to power a talkie?
 JE> You don't need that much - maybe 3 amps, for 5watts.
2 Amps he needs. Maybe 3 if its charging batteries while talking or 
mething.
Geez, makes me love that 110amp cont supply here... Huge transformer. 
Switchmode. MOSFETs. Running a Rockford Fosgate Punch 200ix. A pair of 
FireFox FRX-747s. A headunit. A 27Mhz. A 477Mhz.
... Not a scrap. I was deliberately wasting your time, sir.
