Yeah, I don't get it. Still no luck.

The layout appears to follow the schematic, my board appears to follow the layout. Going to give it one more look tonight.

I have to say, I'm not crazy about this layout though. I'm not sure what I was thinking with the input, output and 9v connections all at the top of the board. I must have thought it had a buffered bypass when I started the layout.

I'll probably redo the layout with better off-board connections. Hopefully in the process the speed switch will work.  

To salvage this build, I'm about to box it up without the speed switch, going to use an oscillation switch instead. The delay modes all seem to be working fine.

My apologies up front if you have the same results, but please let me know if yours works. I'd like to compare readings as what I'm seeing just doesn't make sense.
