Someone did some really sloppy rewiring on my ESI 250DE on the 1325 AC power pack. Ii looks like they added a resister to the output of the bridge rectifier. I still canb not believe that there was no filter capacitor after the bridge rectifier. I also measured the DC output voltage and it read 12 volts which seems a little high ? If anyone owns a ESI RCL bridge please contact me. It would be very appreciated if you could take a picture of your1325 AC power sully board so I could compare it to mine. Thanks, Frank
