This is driving me crazy - if anyone can help , I would appreciate it immensely.
I'm using Ricks schematic Version 2 updated 11/08/10 , all components stock .
The vero layout is from Harald Sabro Bolstad , posted on this forum by ( I think ) Rick .
I have altered the layout only slightly , to avoid any jumpers running under ICs .
I've checked for shorts throughout , and for continuity everywhere I can see .
The test results are :-
By-passed - normal output
Effect - sounds normal , perhaps a tiny volume drop
Audio probe - as effect on pin 1 opamp then the same at pin 15 PT2399 , no sound anywhere else on this IC . A gentle thumping sound from pin 7 on the
opamp , varying with speed pot - I guess this means the opamp works .
Voltages -
IC 1 1) 5.21 V
2) 4.87 V
3) 4.77 V
4) 0.00 V
5) varying 2.5 - 3.5 V
6) " 2.5 - 3.5 V
7) " 1.4 - 7.8 V

8.56 V (normal output of my PSU )
IC2 1) 5.01 V
2) varying 2.49 - 2.54 V
3) 0.00 V
4)0.00 V
5) 5.01 V
6) as pin 2
7 +

0.001 V
9 - 16) all as pin 2 , i.e.minor variation around 2.5 V
Also , I pulled the 2399 from another pedal that was already working , thinking that the new one was a duffer - no change .
I know the answer must be right in front of me , but I'll be damned if I can see it - HELP !!!!!!!!!!!!!
