Bart NTMB 918F oscillation

Sign in to disble this ad
I'm troubleshooting after installing an NTMB 918F. I wired the harness up as the schematic seems to show, but can't get the volume control to function, at all.

The most mysterious issue is weird behavior that happens only when the bass control is boosted. When this control is flat or cut, it behaves normally. When I turn the bass control up, the signal begins to oscillate and distort.

Any ideas? Bartolini is not responding.
