There was a well known problem with the AN1x where an 
audible "popping" & "clicking" would occur when the AN1x was first 
powered up. Yamaha was forthcoming in acknowledging the problem and 
it's resolution. I had the problem addressed by Yamaha while my AN1x 
was still under warranty (purchased autumn '98, repaired spring '99.)

The repair is referred to by Yamaha as a "factory modification". The 
synth will need to be returned to a Yamaha facility. Authorized 
Yamaha Service Centers are not equipped to affect the repair. It is 
a hardware repair and does not register on the diagnostic equipment 
used by your local tech - yes, you have to use your ears for this 
one. 

Yamaha Customer Service will provide a 'Return Authorization Number' 
in advance of the instrument being shipped to them. I've no idea 
what Yamaha's policy on out-of-warranty repairs is or how much it 
will cost. 

Hope this helps.

Regards,
