[ARC5] Help with tuning knob ideas for ARC-5 receiver

[Glen Zook]

Look for a plastic knob from an older AC/DC AM receiver.  Many of those knobs fit a knurled shaft.  Also, you can take short piece of soft copper tubing with an inside diameter just smaller than the spline.  Gradually push it onto the spine connector.  The connector will put grooves into the inside of the tubing without damaging anything.  Then put a knob on the outside of the tubing.
