Re: Missing knob for Tek 576


Hi David,
My 576 has a knob like yours but not exactly the same. The odd thing about the knobs on mine are they only have one flute. The 7000 series knob that Jon Paul used probably had two flutes (180 degrees apart) or 4 flutes (90 degrees apart). I suspect Tek ergonomic engineers realized, between the time the 576 came out and the 7000 series was introduced, that 2 flutes and 4 flutes afforded a better grip resulting in the user being able to apply more turning torque.

The 2 flute and 4 flute knobs are quite common. I have many spares. If those will work for you what I need you to do is measure the diameter of each shaft and send it to me off line at dennis at ridesoft dot com.
