I'd also say pull them straight out. Be careful cleaning them though because I think that they're just plated  had the LA100.

Also, maybe call Rich at signature sound. He's the guy that does my part of the repairs on those at this point. He'll know and likely be able to tell you what to use to clean them as well. 

To clean the knobs while on the unit, try a mild soap and water solution such as dishwashing liquid on a cloth. If this does not remove the "dirt", it is probably because some of the thin plating has worn off the knob from the oil on your fingers. Consider it "patina" and continue to enjoy the music.
