Help with Boss CE-2 Voltages

[astrodave]

Hi Could any one please have a look at the voltage reading im getting from my pedal. The Problem im having is no chours affect at all just clean sound from both on and off.

Power =9.27v

IC1
1=5.39
2=4.47
3=4.46
4=0
5=4.47
6=4.47
7=3.56
8=9.27

IC2
1-8.65
2=4.98
3=8.89
4=0
5=5.00
6=7.78
7=9.12
8=9.27

IC3 MN3007
1=7.97
2=5.93
3=0.99
4=1.00
5=0
6=4.03
7=7.52
8=7.52

IC4 MN3101
1=7.98
2=4.05
3=0
4=5.92
5=0.32
6=7.10
7=2.47
8=1.05

Q1
E=4.98
B=5.29
C=9.27

Q2
E=5.06
B=5.61
C=9.27

Q3
E=0.19
B=0.18
C=8.99

Q4
E=2.12
B=2.65
C=8.00

Q5
E=0
B=0.4
C=6.72

ANY HELP PLEASE

Thanks Dave

I'm out tonight but will sort it tomorrow.

Can you please tell me what voltage you set your trimmer to and where you read the voltage for setting it?  I'll set mine the same and match the dc input to.

0.99 V bias voltage is too low for a proper working MN3007...

voltage at pins 2 and 6 are different (they should be more or less the same) check for a proper square wave with a o-scope

Ok Thanks guys
I set the voltage at pin 1 on IC1(4558). and I will check pins 2 and 6 with an oscilloscope. Thanks once again

Hi Fender3D

Nice square wave at pins 2 and 6

pin2 =5v
pin6= 8v

Thanks

Hi, some pictures of my Tonepad CE-2 Build, I have since re-soldered all the dodgy solder joints...
