Thanks for the info. I tried a new ic with same results, no sound. I will post the readings  when I'm back from vacation. They were still very odd, mainly negative. Again I'm very thankful for all the help and input and time you take to help me figure this out.

Ok I have sound on this pedal but kind of noisy,hissy and not very loud. I have some readings and they seem close to what is required but a few are not exact. Any suggestions? And thank you for pointing out the backwards ic (sockets are now my best ever friend). I hope this is enough info to get an idea on my problem. Thanks again for all the help and treating my newb questions with kid gloves.
pt2399
1=5
2=2.5
3=0
4=0.84
5=2.9
6=2.5
7=0.71
8=0.72
9 through 16= 2.5  (pin 14 was 2.49 but I figured that was close enough)
ic 1 lm78l05
1=0.56
2=0.56
3=4.46
4=0
5=4.43
6=0.55
7=0.52
8=8.90
regulator= 8.96/0/5.0

I think you mislabeled the voltages for the op amp as lm78l05 (that's the regulator).

if so, those voltages look off to me.  probably a wrong resistor value nearby.
always the beautiful answer who asks a more beautiful question.

Thanks for the information and the help. I got it all boxed up and working finally. Turns out a few bad ic's make for an unhappy pedal ( and one frustrated newb builder). Sockets are now my best ever friend : )
Onto the next build project.

It was the op amp. I switched the pt2399 as well after to see if the spare I had was less "noisy" as they say. No difference . I rewired everything as well to be on the safe side before I stuffed it into the box. I have to say it is one cool sounding delay pedal. Really like the swashy kind of tails as they diminish.
