38-690 Treble/Audio Bandwidth
#6

Trying to remember about the cardboard sleeve. I did 2 37-116's and 1 38-116. It seems to me only one of them had the sleeve. they might have been removed in a previous repair. On all of mine, the long shaft has a pin on the end of the flattened end that fits into a hole at the bottom of the slot cut into the shaft of the pot. then there is a little spring clip that takes up any slack in the shaft to pot coupling.


Update: I looked a couple of photos. The cardboard tube is on the volume shaft, not the selectivity shaft. I think the cardboard tube was there to prevent the shaft from wearing through any wires that might be rubbing against it.
