Just placed the order for London Power's SB-2 power scaling kit. Kevin told me it would be really simple considering the fact that the Tiny Terror already has a PPIMV. I'm going to replace the amp's power selector switch (actually, it's a "15 WATTS - STBY - 7 WATTS" three-way switch) with the power scaling control pot/knob. I've never tinkered with an amp's circuitry. Besides draining the lethal voltages from the caps, any other words of wisdom before I begin the surgery?
