Debugging DOD 440 EF

[Deep Blue]

Alright, I built a DOD 440 Envelope Follower using the layout and PCB from JD's website.

True bypass works, and the LED works, and a visual inspection found that the diodes and polarized caps are in the right orientation.  And so is the big, funky component with 5 lugs.

But as soon as I switch the effect on, I get no signal whatsoever.  All of my wiring and soldering is fine - I've checked it all over at least three times.

I swapped the IC chip (which is in the right orientation as well) with another of the same sort and it still gives me the same problem.

Any suggestions?

So, like, what readings should I get from the lugs of the IC chip?  I really really need some help with this.

What is that funky five legged thingy...the VR unit?
 I tried it with LED/LDR [like on EZ Vibe and others], but read that this won't work in the 440.
 There's a widget [I forget the name...Vactrol?' something in the realm of an opto resistor where  the two Variable R's need to be...I got signal [been a while now IIRC] but no wacky sounds like I was hoping for.
 You could post some voltages, [some are better at diagnosing from pin V's than I am but I'm getting to where I can problems], they're fun to look at !!!
 what are you using for Variable resistor units? I'm better at paypal these days and might like to try the right parts like on this one [and others].

I'll take a look, I'm sure someone here that knows more will too.
 Gnd sould be Gnd, whatever the pos should be like 9v or 4.5, and the inputs should be somewhere in between..for starters AFAIK.

For that vactrol or opto-resistor thing???
 I would like to know so I can get one that works for mine
