OK as suggested on his site no direct support for the PCB's but if I post here maybe some help, hopefully.

Anywho, bought the PCB and would like to use NPN transistors and in the documentation it says to not use the charge pump and it's associated caps (2 10uf) and then to jumper the NPN pads together. OK, so E-E, B-B, C-C; correct? And the DC jack will be center pin negative still? Here is a link the the site and the PCB. Thanks for the help!

It looks like the "NPN pads" are the two points under the "LEDR" near the top of the board. That seems to reverse the power arrangement.

Ahhh! Thanks much. I did not see them. I'm guessing connecting the pads will keep it center negative when using NPNs with that board. Thanks again, really appreciate it!
