I am attempting to repair the volume control on a damaged Rega Mira 2000 integrated amp that I recently required. The volume control is a 20 step mechanical rotary encoder with a built-in button that switches to input selection when the shaft/button is pressed (original was bent and damaged). The encoder controls a motorized pot within the amp. Thinking that rotary encoders are standard parts, I ordered a 20 step Bourns encoder with the same dimensions as I couldn't find the original Alps unit. It works fine, however the direction is reversed when turning the encoder; turning it clockwise decrease the volume and the same with source selection. My initial thought is to cut and reverse the traces to the pins on the encoder, but if there is a more elegant solution or maybe a different part that I'm not aware of please let me know. I've attached the schematic I have of the main PCB, the encoder is on a daughter board not shown that connects via the SK3 connector shown in the schematic, this is the encoder that I am using as a replacement.
