I'm new here ( as a poster but not as a reader ) and looking for some help I guess.
I've been trying to finish the ESPs NE5532 preamp for some time now. I built it twice with exactly the same result: no signal out and low voltages on pin 1-7.
I modified the schematic to have a XLR female as output instead of the 10 pin ribbon connector. Pin 9 ("-12") is connected to ground and "out" is connected to pin 2 of the female XLR (pin 3 & 1 to ground). Other that I followed the schematic very carefully.
NE5532:
1. 1.30v
2. 0.83v
3. 1.23v
4. 0v
5. 0.25v
6. 0.84
7. 1.30
8. 18.30v
