Smile Removing the voume/balance knobs

I've also wanted to clean the pots and switches, as the input selector switch would sometimes drop the right channel, but have had no success getting the front panel off.
Do you have any advice for removing the central volume control?
It's the only knob that doesn't simply pull off.
Hi, yes, that knob was a bear for me also. I finally got it though. I was using an allen wrench that was too big. I slipped a VERY tiny bulb into one of the screw holes and peeked at the lit setscrew. It is very small. It takes a 1/16" allen wrench to do the job. I also found that it took two cleanings with Caig Fader Lube / MCL to quiet the pots. I used 100% Deoxit on all the switch contacs. It is working just fine now. I use JBL L100 speakers on my test bench. Quite often they will bottom out while testing an amp with high volume and substantial bass. This Kenwood REALLY was impressive. Same levels, no bottoming out. Good luck on yours!!
