Sticky Knob
Hi Chaps, I wonder if you can help.
We've got a Westerboer VW900 vario with a sticky knob, sometimes it takes two hands to change the volume or turn it on. It's a single input instrument, twist and click the knob to turn on, keep twisting to turn it up. The shaft of the knob (sic) goes through the glass and into the instrument.
Any help on how to make it turn a bit easier? I was tempted to give it a good squirt of WD and some exercise, but I don't know if that will do any good to the insides.
Much love
Heffs
