This is a DENON PMA-915 integrated amplifier. It's a slim, space-saving amplifier. I checked its operation before listing it. Sound output from each selector is fine. The PHONO (for record players) also works. Sound comes out of both speakers 1 and 2. However, when the volume is at its minimum with the PHONO and CD selectors, and the tone control is turned to the right, there is some noise. It's not noticeable when the volume is increased. There is no noise with the VIDEO 1, 2 / Tuner selectors, or when playing back from the tape monitor. I don't know why, but it shouldn't be a problem if you keep the tone control turned to the left. The top panel has paint peeling and scratches. It's an old item, so there is no warranty. It's a used item, so it's not perfect. Please understand this before purchasing.
