I just finished building Deathclaw.  And it doesn't sound quite right. 

Here are my voltages:
9.68v Supply

IC1:  TL072      REG   LM78L05     Q1/Q2   MIN   MAX
1       4.71         IN        9.41          E       1.54   1.54
2       4.71         GND     .5mV         B       2.16   2.16
3       4.70         OUT     5.04           C       2.10   2.10
4       0.0
5       4.70
6       4.71
7       4.71
8       9.40

IC2/IC3     PT2399      PT2399
1               2.04             5.04           
2               2.39             2.42
3                .8mV            .7mV
4                .8mV            .7mV
5               2.75             2.79
6               1.95             2.09
7               2.36             2.86
8               2.65             2.86
9               2.42             2.45
10             2.42             2.42
11             2.42             2.42
12             2.39             2.42
13             2.43             2.42
14             2.50             2.43
15             2.42             2.45
16             2.42             2.42

According to the instructions, Q1/Q2 are MIN/MAX are based on MIN/MAX of the delay.  I get no change going from one extreme to the next.  And some of the PT2399 voltages are off a bit.  Please point me in the right direction.  Thanks in advance.

Tech Help - Projects Page / 8-Ball DPDT Switch

Hi everyone.  First time posting here.  I have a quick questions I'm hoping someone will either respond or point me in the right direction. 

I'm started to build the 8-Ball pedal.  In the notes, it list that I'm suppose to use a DPDT switch from Small Bear.  I order it and it was the wrong size to fit directly onto the board.  I clicked on the link and verified it was the correct switch(Use this DPDT switch: http://www.smallbearelec.com/servlet/Detail?no=43 ordered.)    Has anyone else encountered this?  And what is the correct item number for Small Bear?

Thanks
