I have an L2m that has a 60hz hum.
I've eliminated the external cables and signal path, and I'm now sure it's within the unit itself. It's an older unit, no warranty but in excellent condition otherwise.
Is there someplace I can look up official service centers. I know of some dealers, but they don't do service.
Also, is there someplace I can order parts? I cracked one of the end caps tightening the screws too much... I'd like to buy a new one.
