Default crackling from my source selector.

I have a nu-vista m3 integrated amp and when i jiggle the source selector I get a crackling sound and some times the left channel cuts out.Sometimes I get this crackling and have to wiggle the knob to get it to go away.I seam to only get it when theres music playing.If I stop the cd and wiggle the know I get nothing.Any ideals on how to fix this guys.

thanks
Glen

That's arcing or harmonics caused by the sudden signal changes when the Contacts are making and breaking, popping inrush etc...
You need to replace the contacts or
clean them and cover them with *electrical* contact grease.

EDIT: I don't know what the device is your using I'm only commenting on what I've experienced that matches your symptoms, ie bad switch contacts.

Hi Glen,

My Nuvista M3 seems to have the same trouble.... what did you do to fix the defect?

Thanks!

Switch cleaner is the answer. Or possibly a bad solder joint somewhere near the switch.
