This is a used but working tube PA amplifier. All the tubes test at least good on an emissions type of tube tester. One of the 7027A output tubes has a broken keyway. The tube works great but requires care in inserting it into the socket properly. All three inputs work: 2 microphone and 1 phono. Newcomb rated this at 75 Watts using 7027A output tubes in push/pull configuration. It was tested using a CD player into the phono input in the back using an RCA connector. It was tested using an electric guitar into the microphone inputs using the 1/4 microphone jack. I also used a y-connector so that the electric guitar can be plugged into both of the microphone inputs at once. It was plugged into a 4×12 speaker cab. There are screw terminals for 2, 4, 8, and 16 ohm speakers. This amp will overdrive when turned way up and it will move some serious air. It can also be used in 25 and 70 volt installations.
