[sdiy] Trouble shooting the PV-1 pitch to voltage converter

[Joe Frey]

The PV-1 is a pitch to voltage converter designed by Harry Bissel and I 
know of one person that uses it.
Needless to say mine doesn't work and I'm stuck. I have added a link for 
the original project pdf that has the schematic. There is a link to a 
pdf of my project with voltages listed for ICs, transistors and diodes. 
There are links to a photo of the top and bottom of the board I made and 
populated, Any help would be much appreciated.
