I was cleaning the garage and found this: The case is in good shape and responded well to a slight cleanup. The cord appears intact but I couldn't get continuity across the RCA plugs when I tried it. Could just be corrosion on the plug surfaces, I didn't spend much time on it. Worst case would be a cable replacement. Pretty sure the amp was 1975. Asking $50.00 OBO shipped CONUS, recently saw one on eBay for $100.
