Works as well as the day I first purchased it in 1973 or so. Excellent versatility and sound.

A sweet-sounding integrated receiver loaded with flexibility and options. The specs are top notch and if 37 real watts into 8 ohms per channel isn't enough for you, try getting more efficient speakers. Worth doing a full restoration on. The only slight negative: it uses those funny proprietary plugs Pioneer fooled around with for a few years to hook the speakers into the back of the unit -- but you can't have everything and it's easy to hack one of those plugs together out of an extension cord replacement plug that has screws to open the shell. Even today, the FM Stereo reception from the tuner is outstanding.

My father recently gave me one of these. I love the look, everything lights up and seems in working order. I hooked it up to a set of speakers I know work well and the sound that comes out at full volume (at theoretically 20db) is almost imperceptible. Any ideas on what might be the problem?
