You received 2 100Ohm resistors? You did put one into R2, right?

You mean 100nF? You got 4 of these? You did put the other three in C1, C3, C5?

Weird - that's not even on the parts list. You should have got 9 resistors total, plus the pot.
Persistent vertical lines could be caused by a poor connection. If you post clear
pictures of the front and back sides of you PCB, we'll have a look.
