Greetings .. and thanks in advance for all the helpfull info I found here in the past.

I did my best to follow the "when it doesn't work." guide .. but please feel free to correct me if I've made mistakes .

as far as I know this is a stock unit .. it has never worked for me .. it powers on/off as it should and allows the signal to pass through it .. it does color the sound but has zero swooshing or phasing.

battery = 8.44

@ input = 8.44

Q1
C = 3.744
B = 4.30
E = 2.53

Q2
C = 4.31
B = 4.27
E = 4.31

Q3
C = 4.29
B = 4.27
E = 4.31

Q4
C = 4.30   
B = 4.31
E = 4.28

Q5
C=4.30
B=4.28
E=4.30



IC1 (or U1)
P1 = 4.30
P2 = 4.30
P3 = 3.90
P4 = 0.0
P5 = cant get a stable reading 3.2 ~>8.4
P6 = cant get a stable reading 3.2 ~>8.4
P7 = cant get a stable reading 3.2 ~>8.4
P8 = 8.82

U2
P1 = 4.29
P2 = 4.30
P3 = 4.30
P4 = 8.82
P5 = 4.30
P6 = 4.30
P7 = 4.30
P8 = 4.30
P9 = 4.29
P10 = 4.30
P11 = 0
P12 = 4.30
P13 = 4.30
P14 = 4.30
.

D1
A (anode, the non-band end) = 0
K (cathode, the banded end) = 8.44

D2
A = 0
K = 4.30

I think thats all ~> any help on this would be wonderful!

Thanks ~G
