The Yamaha AN1x Synthesizer mailing list

Hi,

Recently I was cleaning the volume knob with a cleaning specific (smth 
like deoxit), when the synth was on (I know - it was bad thing to 
do);now I hear both channels till the knob reaches half of its way; 
further right (when the overall sound should get louder)the level of 
right channel lowers until there no sound and I hear crackles when 
turning the knob right.  What can I do with it? Is it possible to 
replace the knob with not original part? PLS help! Thx

Here's another plea to the list for an AN1x schematic.

If anyone owns the service manual, it would be hugely appreciated if they would
speak up.  We need this info.

I, myself, am somewhat of a technician, and I know a few experts.  If the
schematic was available a whole lot of questions could be answered.

Have you tried Yamaha? That's how I got the schematics for the EX5, and 
after all it's copyrighted material.

Well, any suggestions will be aprreciated... Guess if you can; the 
problem remains :(

Well, there are cleaning sprays specifically made for knobs and switches 
which clean and remove jitter from the knob's moving parts - plus those 
chemicals don't conduct. You could try to fix it first with such spray 
(small cans don't cost much really). Also I'd suggest you open up your 
AN1x and see the board near the knob if there's any other damage which 
you could clean. There's other cleaning spray for such work.

That repair work is easy to do, and might help unless there's some more 
permanent damage, but as you said the volume works a bit weird - I'd 
assume there's something in the knob moving parts which is conducting 
and makes the knob behave wrong. If that doesn't help, then you might be 
able to find replacement knob from any electronics shop - the knob hat 
is just plastic part you can put to the replacement part as well. AN1x 
isn't that old that it would be hard to find replacement, and that 
volume knob isn't special one like the assignable knobs (i.e. you can 
press is too).

I don't have AN1x service manual.

isn't any special kind...
