I found mine in an antique shop at a very reasonable price. I wasn't expecting much but I was pleasantly surprised at the build quality, sound and most of all its sensitivity. I get excellent reception using a simple dipole antenna. If you don't need a 150 watts per channel (wpc) to drive monster stadium speakers then this may be the gem for you.

Hi there, so this little Pioneer is my first Hi - fi reciver, and I just wanted to say some things about it. The sound is excelent, and you would be hard to find a new unit for under $100 that was even close. That said, it was a little low on power. My inital setup had two small bookshelf speakers. These worked great, and it definatly had more power than the speakers could take. I then upgraded to an old pair of rtr IV model B (which are huge, ineficent speakers). These, were a bit much. To drive the speakers at my listening volume it was pushing 20watts, and that was too close for clipping for my comfort (although, it still sounded great). Now, I am getting a bigger reciver for my main setup, and the pioneer will rejoin the bookshelfs in a bedroom. So, if you plan to power some newer , efficent, bookshelfs this pioneer gives you the vintage sound, without the cost.
