Current Lover 2015 - Clean Signal Only/No Effect

[brucer]

So, I built a Current Lover 2015 ...
- it worked fine on my testing rig before boxing
- once boxed, it gave either silence (no signal) or ear-piercing tone when I operated the stomp switch
- probed it: faint testing rig tone when not touching the probe to the circuit and ear-piercing tone everywhere when I probed
- pulled it out of the enclosure
- checked parts and wiring
- re-ran testing rig:
   - faint testing rig tone in bypass, silence when engaged
   - probed and got input tone at input pad, but nowhere else
- took pictures and recorded voltages:







- followed MB forum advice:
   - checked parts and wiring
   - reflowed solder joints
   - continuity-tested and short-checked all jumpers and off-board wiring
   - replaced all ICs and transistors with new ones from Small Bear
- re-ran testing rig:
   - clean tone in bypass
   - clean tone when engaged
- recorded voltages with new chip set:



Current status: using "S" and "R" to send and return signal to the PCB from testing rig, I get a clean signal only at "R" no matter how many times I follow the biasing instructions.  Rate light is flashing.

I'd really appreciate a hand with this.  Thanks!

Tried to download AND to open the build doc directly. Each time I got a "damaged file" error.

Anyone else getting this?

ADDITION: Why are you getting 9V on Pin 13 of IC4? Should be seeing 0V on there and 9V on Pin 12. Typo??

Got some tech help responses on DIYSB, so sticking with that thread from here on out (http://www.diystompboxes.com/smfforum/index.php?topic=116251.0).
