Hi Renny I put mine together. I used a 15 watt soldering iron on the contol board
250 watt on the power board. I let the 250 watt get completly hot before I heated
the components and board. To keep the time of heating to a minimum. I used sockets on everything I could get a socket for on the control board. On the schematic the "J"
connections are as if you are lookig at it from the bottom but the part is soldered to the top. So when you make the connections to the pot and battery they are reversed. You can check this with a multimeter. I did not use the pad under the caps (could not find it)
I don't know where you could put fins on the spreader. I had mine out of the truck
yesterday it still looks new only 200 miles so far.
