Yamaha mixers - prone to fader problems?

[thinman]

Just posting this out of interest to see if anyone else has had similar problems:

I bought a Yamaha MG166FX mixer off eBay about 3 years back and one of the master out channels was dead due to the master fader being knackered.

I then bought a new MG166C and having had that three years I've had to change the master fader on that too as it went intermittent. Servisol etc didn't do the trick. It surprised me as it's kept covered and hasn't had much wear and tear.

Internally the fader is the same component as most of the other channels but they've been fine.

I expect it only takes the smallest splash of beer to cause a problem. That's the trouble with slider-type pots - they're far mor open than rotary types.
