Hi,I have a Yamaha Electone MC600 organ.when I power up,all seems ok, with
all lights coming on,but NO SOUND!( when auto rhythm selected lights run
ok),I have checked 4 fuses at bottom of organ,all ok!,as I still think
problem maybe blown fuse,if it is a blown fuse,where's it hiding?,if not
could you point me to where problem lies(if its not a fuse!).Hope you can
help,if not,thank you for taking time to read this.

Hi Dex,

Does it work with a headphone? If yes check the headphoneconnector, probably
6.3 mm stereo plug.

Why do you think it's a blown fuse? It would be highly unusual for a fuse to
be hidden somewhere and fuses are almost never the actual problem but an
indication of a problem elsewhere if a fuse is blown.


I would say far more likely the problem is somewhere in the audio
amplification circuit, does the organ have a headphone jack? Sometimes the
contacts in those get dirty or worn so the speaker is muted even when no
headphones are plugged in.
