Gravity wave debugging

[stinkypu]

hi i posted in the open forum but am posting here in the hope someone who can help will see it

i have built this again from scratch and im getting the same signal out as whats going in heres what i posted in the other thread

Hello again guys , I took some time off from pedal building and decided to try this one again!!

so i started with a fresh vero board and ordered some new components

not having much luck with this one ffs :)


so ive got the board populated went over the gaps with a hacksaw and stanley knife to be on the safe side
 at the minute im getting the same signal out as whats going in ( its been a while since i tried this last so some things may have fallen in to a memory hole and i dont remember what i spent days doing last time lol )

one thing i noticed after reading my previous posts was that i had only done a jumper on one of the pots i have found out that what happened is thayt i folded my print out and missed shape 2-3 being jumpered i will fix that tomorrow .

i did remember that the voltage readings can help so i took those before i gave up tonight

i got some funny readings from lm324 with it fluctuating so if i post 2 sets of values for one pin its the lowest then the highest

so heres what i got so far

lm324
1. 1.69-7.2         8. no reading 0
2. 3.96               9. 4.4
3. 4.22               10.4.33
4. 9.29               11. 0
5. 3.09               12 4.33
6. 5.74               13.4.55
7. no reading 0   14. 3.19>5.74

pt2399
1. 4.92             9 to 16 all read 2.46
2. 2.45
3. 0
4. 0
5. 2.59
6 2.39
7. 0.74
8. 0.82

The next values are for the tl072 i'll call the one higher up the board 1 and the lower one 2

tl072 number 1

1. 4.7    5. 9.29          
2. 4.7    6. 4.7
3. 4.67  7.  4.7
4. 0       8. 2.35


tl072 number 2

1. 4.69   5. 9.29          
2. 4.69   6. 4.7
3. 4.7     7.  4.7
4. 0        8. 4.7

So all im sure of at the minute is i havent connected shape 2-3 the rest i was fairly confident i had got right and didnt have any misplaced cuts ,jumpers or components

I hope you can help and that youre all doing well at this crazy time in the world

Cheers

i have fixed the missing bridge and went over the gaps with a hacksaw also have ordered some clips to check whats going on with the signal through the board the varying voltage on the lm324 has me puzzled anyone know what can cause this?

[stinkypu]

so im working through this trying to debug and im using a crocodile clip/probe to see whats happening to the signal and where its going wrong  
i'll add the picture im using to try and show you whats going on (pink is the signals path)

so ive traced the signal to the first tl072 there doesnt seem to be any change in the signal or volume - is this what should be happening?

it seems to come out of the tl072 to jumper from row 4-5 then from 5-11 where there is a 10k resistor first then a 1u electro cap after it - on the other side of the 10k resistor i get no signal so i followed the 1u cap and the signal is there :) it comes out of the 1u and into a 10k resistor on the other side of the 10k resistor im getting no signal there - is this normal?

i havent traced any further yet although it looks like on the other side of the 10k it goes to an 8k2
 the through dim 2-3 and onwards
