How to fix the slop in the Elekit TU-8500 knobs
Default How to fix the slop in the Elekit TU-8500 knobs

When turning the volume or the selector the shaft moves around in the bushing.
This gives a a less then quality feel to the Elekit TU-8500 preamp.

The fix wound up being very simple. I loosened the screws at the shaft coupler,
removed the knob and shalt, then pushed a piece of flat nylon thread (wire
lacing) through the bushing hole and slid the shaft back through the bushing.

The thread takes up the slack between the bushing and the shalt.

It's a very quick and simple fix that improves the feel of the knobs.

Here are a couple of TU-8500 build threads where grommets from Ace Hdwre with a touch of grease were used to solve the slop problem:
