Vintage Tube Amp

Small Tube amp and speaker in metal case with handle. The piece has a foil label on the front that reads “Hollywood Film Company” with “Serial No 121″ and “Model AMP-1″. We believe this is a portable amp for syncing sound to film but unsure of its use. The amp does appear to have one Amperex Bugle Boy tube installed. The piece measures approximately 9-1/4 inches long, 7-1/2 inches deep including the protruding switches, and 6-1/2 inches tall including the handle. It weighs approximately 9 pounds. The fuse holder does not stay attached and my be broken and the speaker appears to have a tear. The top back left corner of the cabinet has a dent.
