Hey Guys, My SA-9500 has two trimmers on the PS board. The service manual in HIFI engine does not contain the instructions for setting the voltages. I assume that's what they are for, like a SX-1250. Seems to be several revisions of the SA-9500 even before they went to MK II. Thanks Jackson
How to set power supply voltages on SA-9500?

Look on the back panel and see if there is a Round label. In the label will be either KCU (Single Voltage 120V US & CAN), GN (Single Voltage 220V Sweden, Denmark, Norway, &Finland ) or D (General Export 120,220,240 V Model). The Owners and Service Manuals are for the KCU version. You need a "D" version set of manuals. Unless someone here has a "D" model configured for 120V you'll have to find the manual or a Tech that knows his way around the switches and the transformer.
