8-30-2015 A customer's extensively modified C128DCR came in with a failed power supply. I could repair it but he wanted an upgrade to a better one, so that's what I did. The switcher board output is +5VDC at 5.5 Amps and +12VDC at 2 Amps, both higher than the original PS. The transformer is 9VAC rated at 1 Amp (old one was 0.5A). The new PS runs barely warm to the touch after an hour. Ray
