Help wanted - a lot of thankfulness to offer!

Hello friendly gurus of the DIYstompboxes domain!

Finished a build from Fuzzdog, the Emperor, a week back and haven't got the damn thing to work yet so I seek guidance from the masters!

Below is the schematic.
http://pedalparts.co.uk/docs/Emperor.pdf

Thing is, the LEDs work, the power jack read 10,2V (close to 9V), the bypass works but no sound seems to come from either channel of the pedal. This was my second build and since the first went so smooth I've learned a lot about troubleshooting and understanding how the pedals are constructed since running into the unknown error of this one.

I've double or triple-checked that all the components are in the right slot and measured all the Voltages on the IC's.

Voltages are posted below:
IC-A:
Pin 1: 5.43V
Pin 2: 5.43V
Pin 3: 4.96V
Pin 4: 0.0V
Pin 5: 5.33V
Pin 6: 5.33V
Pin 7: 5.33V
Pin 8: 10.72V

IC 1 (Charge pump)
Pin 1: 10.74V
Pin 2: 7.10V
Pin 3: 0V
Pin 4: -(negative)3.57V
Pin 5: -(negative)3.57V
Pin 6: 4.99V
Pin 7: 6.69V
Pin 8: 10.70V

IC-B:
Pin 1: 5.52V
Pin 2: 5.52V
Pin 3: 4.98V
Pin 4: 0.0
Pin 5: 5.40V
Pin 6: 5.40V
Pin 7: 5.42V
Pin 8: 10.83V

Here are some pics (one of the front and one of the back).

Is there any other things I can look in to aid you in finding a cure for this sick little pup? Also, the jacks display continuity to each other.

I've searched about half the board thus far and everything displays continuity that's supposed to do it.

Since I'm sort of a newbie when it comes to this (mainly worked with funky-guitar wirings and stuff before) I do apologise if my questions might seem a bit dumb or if I haven't posted all the right things needed for you to be able to aid me.

Thanks in advance, looking forward to see what the experts on the forum might come up with.

First of all, welcome to the forum!

also a newb here who barely can explain technicalities
for me, the first thing I do when troubleshooting is to use an audio probe and see where signal ends. An audio probe is basically a disconnected speaker wire (with a cap to block dc) that you poke around your signal chain. You can just search in google and tons of info will be there about this...

Hi & Welcome, also..

Can you trace D15 cathode/C21 positive leg and take a DC measurement..??

[DDM]

Hello and thank you both! I'll look into the probe for sure!

Also, thank you both for the hospitality!

The measurements:
D15 - 19.06V
C21- 19.14V when the pump is in 18V operation, blinking between 1 and 19V in 9V, not getting a consistent reading there.

Thanks in advance!

[DDM]

Correction: When both sliders are in 9V Operation i get no DC reading from C21.
When they are in 18V operation I get 19.14V

Ok that means that it works...(i think )
Any progress with audio probe?

[DDM]

I think so too according to the sheet. 

I was lacking a few components to make the probe so I'll get them tomorrow and get searching!

Again, thanks thus far!

[DDM]

That audio probe is a really cool tool in combination with a looper pedal! Thanks for the tip.

The pedal is now up and running, the electrolytic 10u caps was the culprit.

Thank you so much for your help! 

[antonis]

the electrolytic 10u caps was the culprit

Shall we put the blame on caps or on the builder..??
(defective items or reverse placed..??)

[11-90-an]

the electrolytic 10u caps was the culprit

Shall we put the blame on caps or on the builder..??
(defective items or reverse placed..??)

At least nothing exploded...

[DDM]

Blame the incompetent builder that got a cold solder-joint in one of the caps 

Nothing blew up and the pedal is a delight to play!

Thank you all for your assistance, I got a feeling this might be an addiction I'll have a hard time to kick!

[11-90-an]

Bah! What addiction?
