Hi,
I just bought a GF-777. It is in beautiful condition but something is not right inside. When I switch it on the power light turns on accompanied by a loud hum. If I turn the volume up, even a little bit a loud repeated 'galloping' sound is produced. This happens irrespective of which input is selected. I have attached a video which shows this best.
I hope someone here has encountered this before and that it is an easy fix.
Any help would be greatly appreciated in diagnosing and repairing this piece of audio history.
Thanks!
