Mine:
Here are voltages just taken from my Little Angel, which sounds the same as the breadboarded version I did you soundclips on. Speed at 3 o'clock, Depth at 12 o'clock:
PT2399
1: 5
2: 2.38 to 2.42
3: 0
4: 0
5: 2.75
6: 0.61
7: 0.88
8: 0.88
9 through to 16: 2.41 (slight movement)
NE5532
1: 0.13 to 4.9
2: 2.9 to 3.2
3: 2.7 to 3.1
4: 0v
5: 4.79
6. 4.9
7: 5.14
8: 9
So it seems you have some way-off voltages at:
PT2399 pins 5, 7, 8, 9 ...you get 5V on pin 5? Pin 7 being ground is causing an issue elsewhere.
NE5532 pins 1, 2, 3 ...particularly concerning as these should be moving, which says the LFO isn't running.
NE5532 pins 5, 6, 7 ...pin 5 is way off, fix that and 6 and 7 might fall into line.
Solder bridges and/or incorrect resistor values is my guess.
