Hi Bill,

I listed the Digikey numbers to make them easy for people to order the parts, if there is an error please let me know. Be sure to use a heat sink, since running at 3 amps can create a lot of excess heat plus these can supply peak currents up to 6amps. We took an old car amp apart and use the heat sink from it. Mounted all three boards to it, even put a fan from an old computer. Not even warm to the touch after hours of use. Any block of metal should do, just need to disperse the heat around.
