Thanks relic38,

Just followed your tips, and added 3 chips..

I used these Goot Heat Clips, and they have definitely made this little mod a way lot easier.

the springs are rather stiff, abut will hold the small parts in position even better.. Now you`ll have 2 free hands again to solder.

little pricey at amazon, but worth the money, especially if you can find them for cheaper! great for shaky hands!

Just a suggestion, I use tabbing wire for a lot of this. This is the pre-tinned flat copper wire used on solar panels, not the tiny stuff but the “Bus” style that handles more current. The plus side is all you have to do is touch it with a soldering iron to make it stick. Wrap a small piece on the edge of a driver board tack it on both edges, instant ground. Reflector contacting the MCPB board? Tack small pieces to the contacts and solder the driver wires to the underside. Works great.

Photobucket changed to a pay system, and I put these on there. I have requests to update this thread, but unfortunately I do not have time, sorry.
