Schematic:



Layout:



I believe the transistors are in backwards as the collector in the layout would go to ground instead of the Emitter?

I'm asking because I just picked up a PCB that I did before and never debugged it.  Now I know why.

I mean no disrespect to Markm I love his layouts.  I just wanted to let you know that there is an error in it. 

Unless I am wrong?

Different transistors have different pin outs... There is no denotion of Collector or Emitter on the layout, I think it was assumed the builder would compare the schematic to the datasheet of the transistors to the layout.
