I just wanted to bump this topic. I recently bought my first Kohout board and could not be happier. It's a System 7-11B Power Supply and it is soooooo nice. It was packaged perfectly, has a great manual with schematics and is built solid as can be. Gotta love the rotary switch with actual voltage display! That is definitely a major step up from an LED indicator!

From now on Kohout will be my first choice on any board they sell.
