Hi i want to buil this effect, after many search i found this website :
http://sounddiy.free.fr/AnalogLo-fiLooper.html
but there is no pcb layout on it... So with the help of google, i found those things:
If someone could help me for redraw a new pcb layout with the pitch control mod and the tl071 in place of LM386, it will be very nice!
I also have a bill of material (in spanish but easy to understand):
R1, R2, R3, R4: 1K
R5: 0R
R6, R7, R9, R10, R11, R14: 100K
R8: 3M2
R12: 10K
R13: 180K
R15: 4K7
P1, P2, P3: potenciometros de 100Klog funcionando como resistencias variables (la pata del medio y la de un extremo van conectadas)
C1, C2, C12: 100uF
C3, C4, C6, C8: 150nF
C5, C9, C11, C13: 10uF
C7: 10nF
C10: 1uF
C14, C15, C16, C17, C18: 100nF
D1, D2, D3: 1N4148
LED1: led bicolor (como 228-5641 en
http://www.amidata.es)
Transistor: BS170 (el que se usa en el millenium bypass)
Operacional (O.A.): TL074
Puertas XOR: 4070
Amplificador: LM386
Sampler: ISD25XX (2532 o 2560 recomendados)
In advance thanks for your replies! (sorry for my mistakes, i'm french and i'm not very good in english...)
