Hello all,
I must say that I have had some serious problems running Yamaha gear
off other brand power supplies. I've got other gear that works on off
brand stuff fine, but not my Yamaha gear. These problems show up as a
really nasty hum and a bad connection to the keyboard. Both are really
irritating. The Yamaha power supply maybe isn't as cheap as an off
brand one, but I lost my patience with those cheap things a long while
back and I've never regretted it. I've seen more lousy sound problems
generated by cheap power supplies than I can throw a stick at... Of
course, I have also picked up some sweet deals on gear people sold due
to problems that were completely coming from the cheap power supply. (I
got a mint Pc1600x for like $120 from a store on the web and the power
supply was totally wrong for it - a new one from Peavey completely cured
this machine where it was functionally useless when it arrived. If the
guy had just gotten the right supply, he'd probably have never sold it,
or at least gotten more for it, but it didn't work worth a damn on that
one it came with. The moral is - if it is acting weird - check the
power supply! Just because the display comes on doesn't mean it's got
enough juice to run right.) These machines are very sensitive to power
and if it isn't getting the proper clean DC that it is designed to run
on you can fry stuff or get these other stupid problems. Why cripple an
excellent instrument with a cheap piece of junk to save a couple of
bucks? I've heard several stories of people actually killing their
boards when their cheap supply died on them. That suddenly becomes a
VERY expensive power supply. Spend the extra $5 or $8 or so. I've had
four Yamaha boxes and I've never had one of their power supplies die on
me, but I might be just lucky. Don't know. One thing is for sure - it
WILL work right on your AN1x and it will fit.
My An1x is running (in the US) on a standard Yamaha PA-3B power
supply. I know a lot of people have the attitude that they can save a
few bucks and there's no difference. Most of the time probably there
isn't, but my personal experience with 4 Yamaha synths leads me to
believe that there is something different with their power supplies -
maybe a voltage regulator in there somewhere, or maybe it isn't exactly
9 volts - who knows? I'm not an electronics wiz. One thing is certain,
I'm too old to deal with that kind of sonic chaos for the cost of a
Mcburger meal...
Sorry about the rant... I hate paying more than I have to for stuff,
and believe me I know what it is to be tight on cash. These boards
aren't cheap for me. The sound is very important to me and I refuse to
risk them with cheap electronic junk. Yamaha has a reputation to keep
up. And they know the specs on their gear better than anybody. There
are a lot of places where you can save a buck or two, but my personal
opinion is that power supplies for keyboards is NOT that place. FWIW...

Lecture over... It won't happen again,
