Question
QUESTION: My Yamaha organ has pedal malfunction. IC needs to be replaced YM604. Problem: pedal hums nonstop even after foot taken off pedal. Where can i locate this sparepart?
Thank you

ANSWER: Hello Vee!  I assume you have tried swapping IC's around to determine whether the problem follows the chip or stays in the same position.  If the problem follows the position of the chip in question, then yes, it is likely the problem is the chip itself.  Go to http://mitatechs.org/manufacturers?page=7

I wish you success!

QUESTION: Thank you for your assistance.unfortunately, no luck. anywhere else i can source for this?

Answer
I assume you tried contacting the Yamaha company directly via the information provided on the MITA website and did not received a response.  However, you can contact MITA directly and ask them to help locate a part by having them place your request on a list which reaches out to all of their members world wide.  Surely someone has the part.
