I have a Korg Concert Piano C-15, which is aging. I believe the electronic components are going. Capacitors tend to go first, so I've replaced most of the polarized electolytic sapacitors. It still fails to make sound except a brief "burp" when powered on. I suspect it is the main amplifier board as it handles greater power and has more and large capacitors than the synthesizer board. A few questions:
1) Do you know any source for board-level spare components for the Korg C-15?
2) Is it worth it? It seems a waste because the keyboard is pretty nice - full 88 - and probably the most expensive part of the piano.
3) Can the electronics be replaced with newer components so that the chassis and keyboard can be retained? E.g., new amplifier.
Considering the cost when new, I would have expected Korg to use high quality long-life electronic components. Apparently not. Good old wood and sounding board pianos have a far superior lifespan. If the Korg is trash, I'll probably return to accoustic.
Please assist in resolving this problem.
I didn't find the right solution from the internet.
