Hi all,
I have an HGS 10 I bought new many years ago. Recently, when plugging in the AC power cord, it emits a hum. The sound is a constant pitch which starts loud and completely fades away after about a minute. It does this with or without an IC connected. Turning the volume knob has no effect. Has anyone had this problem? Does anyone know how to fix it?
Thanks,
henrylr
