Mission 1: Blue Clipper

[leopoldoghost]

Hi Everyone,
this is my very first project, and, as it should be, it doesn't work 
Now, i've read the Debugging guide (god bless the writer), and i' ve found out some "malicious" components (and replaced' em).
Still don' t working... 
I have some suspects for the IC...
well, i really can't get out from this situation, so, i'm imploring community's help
According To DEBBUGGING Guide:

1 - [ISSUE] no sound at all (i'm unsing no bybass)
2 - [CIRCUIT NAME] Blue Clipper
3 - [CIRCUIT SOURCE] http://www.tonepad.com/getFileInfo.asp?id=93
4 - [CIRCUIT MODIFICATION] NO
5 - [PART SUBSTITUITIONS] YES:
R1 -> 220k
R2 -> 270k
R6 -> 12K
Equivalent Diodes (cant' remember the name )
6 - [GROUND CONVERSION] NO
7 - At this point, i should've posted the voltage for each pin of each component but i've noticed something strange.
     in some components, the voltage is 0.00 (?)
     If this can be useful, i can write the full list, but now (Hoping that my suspects are founded) i'll write just the IC's voltages

TL071 (8pins)
approx. 9,52V DC IN (Battery)
pin 1: 0,05
     2: 9,10
     3: 0,00
     4: 0,05
     5: 0,00
     6: 0,59
     7: 0,00
     8: 0,00
(pins 3,5,7,8 seems to be dead, not, as 4 and 1 that moved a little my multimeter)
 
thanks in advance for the Help

Substitutions are fine.

Did you use TonePad's board? Or etch your own? Or perf-boardf?

Pin 7 is supposed to be +9V. It comes right from the battery via any switch, jack, or other stuff, to "+9V" on PCB then a half inch trace to IC pin 7.

Pin 2 must NOT be +9V; this says there is something else wrong (which is why I wanna know what board you use).

I' ve used a Stripboard, than, "draw" the circuti on it.
some photos can be useful?
