Vern, There are basically 2 power leads from the power supply. 1 is a multi-wire cable that plugs into the card cage usually and the other is a large, #12, two wire that goes from the heavy terminal on the rear of the supply to the main chassis set of terminals, usually in the upper right.
The multi-wire cable hopefully is there. It is just wirings coming out of the PS chassis and carries the low current 9.6V and 13.8V. The larger 2 wire is easy to make and supplies the power for the PA. 73, ron, n9ee/r >From: [EMAIL PROTECTED] >Date: 2008/03/29 Sat AM 07:51:35 CDT >To: Repeater-Builder@yahoogroups.com >Subject: Re: [Repeater-Builder] Re: Compa Station Help > >The reason the power supply leads are missing is that I >got it from the local used supply store.
