Please confirm this, you got -0.013v at pin 7?So I measured FI for +15V at NE5534 Pin 7 and I'v got -.013V at pin 4 I've got -14.99V Checking TL072 at pin 8 I've got 12.14V and at pin 4 I've got -12.03V
For all NE5534, or just one?
If only one, with the GSSL switched off, set your meter to continuity mode. Put one probe at pin 7.
1. put the other probe to ground (any solder point labeled "0" on the PCB)
2. if no beep, move the probe to pin 3 of the 7815 regulator.
3. report back here
