HOwdy!
  3rd Sunking build with the etched board... populated the board at the same time as the 2nd about a year ago. That one worked well.
   First thing is to turn it on... oh, forgot the IC's... got 'em in... nothing... okay then realized that I'd mucked up C6 & C8 by a decimal point here and there. Rectified that.
  Works now... but there is no warm fuzzy like with the other builds.... I even put in a .1uf for the C14 which tamed a lot of the top... but what could be draining the low end? The others didn't lose so much of the 'girth' to the tone...

voltages seem okay:
   9.14 in from a Godlyke Power-all adapter

IC1
1. 4.59
2. 4.59
3. 3.52
4. 0
5. 4.58
6. 4.60
7. 4.62
8. 9.14

IC2
1. 4.67
2. 4.59
3. 4.56
4. -8.7
5. 4.58
6. 4.59
7. 4.51
8. 16.50

IC3
1. 9.14
2. 4.68
3. 0
4. -4.25
5. 8.70
6. 4.45
7. 5.78
8. 9.14

I've been through all of the resistors and caps and all are the right #'s... don't think anything is fried.
I switched IC 1 & 2 out with the TL072's in my awesome 1st build...
no change...
pulled the 1N34a's and stuck in some BAT41's.
I have the switchable Buffer/True Bypass mod that works great in the others.
IC1044SCPA is the charge pump like on the others...
Any ideas?

Thank you Dr.!
Yeah... I guess the way is to check the schematic against the tracing..

cheers

 Hi folks...
I etched a Wolfshirt and a Sunking. Wondering if the component numbers that are listed under the fabbed version of the Wolfshirt match up to the etched version... since there is only one list.
  I discovered after mostly populating the Sunking that there were 2 seperate numberings and (alas) I used the one under the Fabbed version...

thanx!

Great... thanks. Didn't want to buy all new resistors. 

I noticed on the part layouts there are some resistors that seem smaller than the normal 1/4 watters.
For instance on the Sunking board, resistors 1 - 7 are tiny compared to 8, 9...
If this seems like a a silly 'noob' question please forgive... but enlighten.

Thanks
