For the voltage mod, are you just bridging the pads with solder, or are you adding some resistance?
Also, from your last post, am I correct in assuming you are running the PS at 220 for the savings? I don't think mine powered on at 220V
Thanks melmo
A couple of tips: I noticed that the power supply has a switch on the side to select voltage. I had been running with it set to 220V, and was only pulling 58 watts from the wall. It was pretty stable like this at 850 MHz so I measured the voltage on one of the plugs and the power supply was only providing 10.8 volts. After switching to 110V, I was reading 11.9 volts and power usage went up about 10 watts.
After doing the voltage mod, I'm running stable at 401 Kh/s and pulling 82 watts at the wall for my 10 units.
