Has anyone built Dark Kittens version of the board?  I've read all the posts, I looked at his pictures, and I cant tell what all his solder side jumper connections are. If anyone has built his board successfully, please indicate what the jumper connections are.  I have attached a photo of my board with the bottom connections in question circled in red. thanks

Hi Wil

I think that you should post a photo of the top view looks like there could be some components in the wrong place.

Thanks Xavier, I am going to pull the data sheet on the transistors to double check if I installed backwards. Thanks Japanese for the the info on R30!, and the good picture of the layout and parts!  I only wish I had the good pic of layout 6 months ago!
