Hello,
EDIT: I thought i had double checked, anyhow, it was a wrong resistor, all is well!
On my second 1176 i get heavy oszillation throughout the control amp. Audio is passing fine, but compression isn´t working as expected. No idea what´s wrong. The oszillation can be seen at almost every point in the control amp, starting with the input connection 22 (with switching boards disconnected), right at c17.
Also i noticed that my negative supply drops to about -5v with the unit connected.
Any idea what this could be?
I suppose i should replace the transistors q12-q14. Unfortunately i don´t have any bc107s left. Can i try a 547 instead?
