    Odd Sumo The Nine Plus

    Good lord AK has changed a bit since I've been gone... I've got a bit of an oddball, here. A disjointed album of photos can be found here: http://imgur.com/a/O95G4 I can't figure out what's going on, here. I've had this amp for a few years and I'm now finding time to get into restoring it...
