Sound Input is a single RCA Mono port. Comes with single Mono RCA cable and AC power cord. This portable PA tube amp is in very good fully working condition, and looks great for its age, minor scratches here and there on the exterior case, the unit has an overall patina which is shown in the photos. The POTS work well and do not seem to generate much if any scratching sounds when turned. Unit has been fully tested, comes with original JBL speaker, all parts seem to be original. When using Vacuum Tubes will glow and generate a slight burnt dust smell, but is safe is cooling vents are not blocked from cool air flow. Would make a great functional Movie/Photo Prop. Also a great practice amp. Uses 120V AC at.
