I wonder if by chance a "Weighted knob" was installed in place of the
original? Or... Could the original knob have had some weight added to
make it spin? Maybe placed on the unit accidentally or just because it
was a handy knob?
Just a thought. GL with the tuner!

I don’t see a spring to use to adjust the tension on the shaft so that it stays in place once adjusted for proper tuning. Can someone explain to me how to tighten the tension on the capacitor shaft ?
