[sdiy] Advices for restoring an old Roland SH2

[Jean Bender]

Hi !

I've got a Roland SH2 to fix. It's working propoerly, except a "buzz"
that appear around the 50hz  : this buzz is always here once the synth
plugged. I imagine a problem around the power distribution ? I should
chek all the caps and replace some of them ?

Also, the main output has no gain, and i have to use the headphone
output. Would somebody have an idea about that ?

Thanks for any advice or answer !
Best.
