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 ------------------ Travlin' Easy

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.
