K-3. Knob to adjust power/ problems


Peter Reinzuch
 

The knob you spin to adjust the power output does not change the K-3 power output.  You can spin the knob and the power output does not show as changed. It can take many minutes to adjust the power output In a jerky way so I can drop power to have the Amp on.   Is there a way to tighten the knob so it steps up or down smoothly?  It basically spins freely now?

Sounds to me that it is a faulty encoder.

I had the same issue... Sent to factory, took three weeks, and works now... I had them replace all 4 while they were in there.

I had a similar problem with AF knob on my K3 and it was a split knob that did not tighten down on shaft, so remove knob and turn shaft if problem is gone possible knob if it persists it may be a bad decoder
