This one was a long time in the making. The case is cherry, the face plate and knobs are copper. The left knob is input select, center volume, and the right knob is a rotary dimmer switch for the (incandescent) backlight on the volume knob. Sounds absolutely beautiful, looks just as good, with more coats of polyurethane than I kept track of! Thanks to all of the people at diyaudio.com, especially BrianGT, who made the PCB boards I used, and to my then landlord Steve who let me use his shop.
