Thanks!


the only problem is the amount of transistors that i need to purchase

"Within a population of 150 transistors, you can easily get 12 sets matched to O.1V VGS at 200mA."

Builders are using different PSU boards either from Peter Daniel, BrianGT, or something of their own. Each builder is left to specify their own PSU parts.

A good source for matched Mosfets is our fellow forum member jackinnj from www.tech-diy.com. He has excellent prices and ships fast.

The KC006L is a CL60 inrush limiter. Any rectifier diodes you find acceptable will work, however some PSU boards might specify specific package types. The 30U60's should work, they are specified at 30A at 600v.

The boards arrived a little late. I'm planning on picking them up late this afternoon or Friday. Depending on work.
