Subject: Re: [TechAssist] Re: Ppanasonic Stereo SA-AK78 Power Supply Sch Date: Fri, 13 Dec 2002 22:43:53 -0500 From: Al Gutz <alg@xxxxxxxxxxx> To: techassist@xxxxxxxxxxxxx References: 1 , 2 Checked the output section on this, No extra shorted pins on the output ICs, closed the relay in the power supply and had + and - 66VDC going to the output ICs, there is a regulatour STK470-050 also in the power supply. I have no idea what this should put out on what pins and cables are too short to run unit without completely reassembling it. Would someone have a copy of the schematic available for the power supply and control circuit on this?
