Yamaha Digital Reverb EME-1

[Stojke]

Hello, i have an "Yamaha digital reverb EME-1" device.

The device emits strong buzzing/noise on the output, that after some time stops.
The buzzing/noise occurs only when the device is turned on.

I have tried replacing the main capacitor, but it doesn't solve the problem.

If any one has experience with this device please tell. Thanks.

it may be an earth loop type problem.
possibly a ground (earth) wire or connection has failed
check cable connections in and out of the unit.
check cables between instrument and unit and unit and amplifier. Make sure all cables are ok
