I have a sparkletop suitcase from september 1964 which I've owned for more than ten years. I've finally pulled it out of storage and started the process of restoring it. Does anyone have pics/schematics and knowledge about the Jordan amps and preamps? There seems to be only a jack out of the preamp amd since the poweramp is gone in the cab I'd like to know how it works. Was it a poweramp with modules design like the Peterson? Any info is appreciated. If someone should happen to have a Jordan poweramp around I would be interested in buying... :-)
