This was the top of the line integrated amp from Pioneer back in 1974.
It was rated at 60 watts per channel into 8 ohms and had three sets of speaker outputs.
This model came with a ton of great features. Get this, there were three separate volume controls on the back for "Phono 2", "Aux 2" and "Speaker B". It had lots of flexibility. 2 Tape, 2 phono and 2 aux inputs means you can hook up lots of components to this wonderful amp. It's very sturdy and I love the solid feel of it. The stamped face of it. All 40 pounds of it. A true throwback to a time when quality was king. Here's a picture of the second I've been lucky enough to find.
