DBX CX-3 Preamp Service Manual

I own three of these units and managed to get two of them in working order without use of a service manual. The third is proving to be a bit of a challenge so if anyone comes across a service manual, I would greatly appreciate the upload.


Re: DBX CX-3 Preamp Service Manual

What problems are you having? As you probably know,the power supplies should be the first suspect. The 8 volt (actually 9) regulators tend to go bad. Check for the voltages on the PS board connectors. Next would be capacitors.
