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
