Aion Refractor (125b) no sound in buffered bypass

[Governor]

Hi, I just completed a build of the Aion Refractor (125b), great board and fun build!  In true bypass mode the pedal seems to work fine, all controls working ok, signal passes through when pedal is bypassed, however in buffered bypass mode the pedal still looks to be working ok, however there is no signal pass through when the pedal is bypassed (stomp switch off).

I can seem to see anything obvious on inspection, I've built over a dozen pedals now and am competent with electronics and soldering. I also test every component individually when putting them on the board and rarely have issues,  so this has me a bit stumped.  Has anyone seen this before?  I might look through the schematic bypass section and try and do some fault finding and reflow some of the soldering points. 

I built it completely stock to the documentation, used D9E diodes, IC3 is LT1054 and Z1 is 4744A.

well, yes, that's good to link to the documents. only, we know the documentation is *error free*, we want to try work out what is wrong with that which you have built, which, as it happens, we can't see.

Ok, so I found the culptrit.  There was a single strand of wire on the main board where the jumper goes to the foot switch board (the earth jumper wire) that didn't make it through the solder pad hole and must have made contact with a nearby resistor.  It's all working, and sounds awesome!

Just one question though, looking through some archives i found the recommended IC pin voltages.  Mine pretty much lined up with these except for IC3 pins 6 and 7, these voltages are about half of what is recommended.  looking at the schematic, these pins aren't connected.  Does this sound ok?  I also used a LT1054 for IC3 whereas the recommended readings were done using a TC1044SCPA.

if all the rest of the circuit is present and correct, and two pins that are not connecting to anything are a leetle off, it is a simple matter to look the other way, get the screws into the baseplate, pretend you never saw me, ok?
