Line6 DL4
« on: May 05, 2006, 03:34:45 PM »
I'm trying to fix a Line6 DL4 for a friend and I'm finding that none of the digital chips are getting any supply voltage. The AC is getting rectified to ~13.6V and I've traced it around to a relay and two maxim regulators. The regulators are not being enabled and I'm having trouble finding what controls the enable line. I've also noticed that the MAXIM regulators are rated at a maximum input voltage of 11.5 volts (absolute max of 12V) and this unit is putting 13.6V+ on them. I'm sure the supply will sag some once current starts being drawn from the supplies but it just doesn't seem to be good to have almost 20% overvoltage on the input pin at any time.

Anybody worked on one of these?

I started out with nothing... I still have most of it.
