Vintage Onkyo P-3160 Stero Pre-Amplifier and M-5160 Stereo Power Amplifier. From the Onkyo R1 line. I believe these date to the late 1980s. Minor wear but in really solid shape.
Both were tested and sound fantastic. Tested both channels but not every input. From the estate of a music collector and was being used recently so everything should be just fine.
I also have the Tuner, Double Cassette Deck, Turntable and CD Player from the R1 line that went with this stack.
