Members rintincop Posted May 5, 2004 Members Share Posted May 5, 2004 Now I understand why Yamaha makes these cheap PA-300 plastic external power adaptors. If you step on it it breaks. I have one that just suddenly stopped working without stepping on it.The cheapest one online is $69.95 ($89.08 list) What a rip-off! Link to comment Share on other sites More sharing options...
Members alby1 Posted May 5, 2004 Members Share Posted May 5, 2004 The external wall wart on the Yamaha P90/P120 was a surprise to me. Makes these keyboards more like a home keyboard than a gigging keyboard. I am still looking where I can put the batteries in so that I can busk with it. As you can see on my previous post I broke my music rest on a gig. Its only going to cost me $25.00 AUD to replace (ex shipping costs). It will take 4 weeks from Japan. regardsalby Link to comment Share on other sites More sharing options...
Members scubyfan Posted May 5, 2004 Members Share Posted May 5, 2004 Many manufacturers incorporate a unique power supply so that you have to buy the replacement from them. It wouldn't take much effort to do otherwise, but they want their dough. Link to comment Share on other sites More sharing options...

Members Fancy Fingers Posted May 5, 2004 Members Share Posted May 5, 2004 Is it really that special? The plug looked quite standard (perhaps a bit on the large side though). It's easy enough to find a universal adaptor where you can select the voltage and plug. Cost about $10. If the new adapter plug doesn't fit then solder on the old one. That's probably what I'd do.

Members Pilot Posted May 5, 2004 Members Share Posted May 5, 2004 You don't need a Yamaha PSU for a Yamaha keyboard. I've never used a Yamaha PSU on one of my PSRs and I use a cheap homebrew PSU on the other for gigs though it did come with the official PSU which I leave at home. As long as it's good quality and meets the spec for voltage and current it doesn't really matter. If the P120 is like PSRs. the voltages are stabilized internally and the speaker driver circuits are good for 25 volts - they're the same as those used for car audio.
