Stage 3 continued
Construction
The rocker switch is an illuminated type (DPST), but it turns out it didn't work when I used only one side. Doesn't matter as I read on some other site that leds can make things sound worse.
I connected all the RCA grounds from one to the other and then took one single wire per channel and attached it to the star ground. You may also notice that I did not use the extra pair of output RCAs to the left. I got lazy and will jump these from the main outputs in the future when I am ready to use a subwoofer. Wire used throughout the power supply was mostly 18-19-gauge silver-plated copper wire with a Teflon dielectric. Everything else was Kimber TCSS 19-gauge copper wire with a Teflon jacket.
