Not having any luck with flangers at all... Here is a start for the voltage readings. I did not complete this because something seems VERY off. Can someone with more mxr flange experience tell if this is fubar and I should scrap it?
IC1:

14.81

IC2:

Don't scrap it yet. You need to put the pin numbers next to the voltage readings. The only thing close to +15 I see is "14.81", but it's unclear which pin. That would be OK for pin 8.
IC2 doesn't have any sign of power. Should have +15 on pin 8.
IC7 and 8 supply the power to the rest of the board. Check those. You need to get +15 on IC8 Vo, and approx. +7.5V for "VB."
+1 for labeling the pins. Need to post properly labeled voltages for ALL of the ICs before anyone can assist.
Also, post voltages on the regulator ;)
My bad. The pins are ascending order... IE
1
2
3
4
5
Etc...
I should have said something.
If that is the case then there is definitely something wrong. Should NOT have 14.8V on Pin 5 of IC1
Are you using an LT1054 for IC7? Have you double checked ALL component values and cap orientations?
Can you repost with ALL voltages for ALL ICs and the regulator?
I just noticed I used bc549b instead of c. I just ordered some bc549c. Could that be it? Should I continue to check voltages or should I wait till I replace the npns?

I doubt it. You really should repost your source voltage and new reading at the pins of all the ICs. Make sure you properly label them! ;)

Is my pinout ok?
I forgot to mention I am using 9volts as my source (1spot).
Just went through this again and I am at a loss. All the parts seem to be correctly oriented and soldered cleanly.
