Well, mine's starting to act up. I have to unplug the adapter end and put back in very gently now.

Anyone selling an extra cord?

What kind of a profit do you think they make on these power chords. I had a quote of $165 for a power chord for my Think Pad laptop. Not nice, I did not buy it.

You might want to take your PSR to a dealer, try another PS, and see if it is the PS or the jack in your 3K before you pony up for a new PS (though a spare is never a bad idea!)...

The power supply for the PSR-3000 has an enormous number of internal components, which was surprizing. It provides a very clean 16-Volt DC signal that is highly filtered. I don't believe it is overpriced. Some of the other's I've seen are nothing more than a few diodes and a step-down transformer, and they sell for about the same price, which is way too much for what is inside.

Zuki, The problem with your system may not be the power supply at all, but instead could be related to the keyboard connector. If that connector has broken free from the small PC board it would produce the same, intermittent results. Another possibility is a cold solder joint where the connector attaches to the PC board, again producing the same results. Cold solder joints are not at all uncommon with any electronic device. Fortunately, this particular board is not that difficult to access, but you still have to know what you are doing in order to facilitate a diagnosis and repairs.

Good Luck,

Gary

The simple and IMO "obvious" solution to this problem is for Yamaha to build the power supply into the keyboard, and use a power chord like what you find on something like a Motif XS, or other pro workstations.

People so often complain about "weight".., ask yourself what's more important.., a good solid built in power supply that would only add a few pounds to the keyboard, or an external supply and flimsy connection ports that are more prone to breaking-thus resulting in you replacing your power supply or connection point?

One of the reasons the power supply is "external" is because there has been such a big issue about weight regarding arrangers over the years. To me it just seems more logical to put the power supply back into the keyboard with a good power chord connection. Yamaha knows you guys use the PSR-3000 for professional work. If you start asking them to put the power supply back into the keyboard, they just might do it. Just my two cents.

Squeak, trust me, it's not weight, it's economics. It's a fraction of the cost to use a wall wart. It's done to keep the cost down.

I was always told by Yamaha it's a weight issue too for the consumers.

Yea right! if they put it back inside they will lose the millions of dollars world wide on selling Ac Adapters when they eventually burn out, buy a back up, or better yet there are dealers charging extra for them on the initial purchase to the unassuming buyer.....its all about $$.

Besides allowing the instrument to weigh less, and to run cooler, an external power supply is also popular among manufacturers because:

1.Instruments sold in the global marketplace don't need to be individually configured for 120 volt or 230 volt operation. Just sold with the appropriate AC adapter.

2.The instrument itself doesn't need to be tested for compliance with electrical safety regulations. Only the adapter needs to be tested.
