[TenTec] Curiosity Question

[Dr. Gerald N. Johnson, electrical engineer]

There's a star wheel that a ball rides on to make the shaft position
detent. Apply a dab of white grease to it to prolong its life. Then make
sure the looseness isn't the knob. Tentec knobs aren't the strongest
things and the bandswitch knobs seem to be the first to split and get
loose on the shaft. I wedged a bit of wood in mine to hole the split
from getting wider.
