Pioneer SXD-7000 Any Info on this BEAST ?

Try searching using SX-D7000. It was made in 1980-1981 era!! I saw several links using google.

Let me know if you can't find what you want and I will ask my wife to try to get some info for you at work. (She works for Pioneer here in Ohio)

Here is what I found at this site:

SX-D7000 Receiver — The D7000 is the big brother to the D5000. While being basically the same layout, it is an inch wider and 5 pounds heavier. The biggest reason is the increase in amplifier power, which is rated at 120 watts per channel with less than 0.005% total harmonic distortion. The D7000 also has a few more controls, such as a C speaker switch, tone on-off, turnover controls for the bass and treble, a display dimmer, a second phono input, and a MM/MC phono preamp control. Moving coil phone cartridges were just coming onto the market at that time, and the D7000 was the first Pioneer receiver that could directly connect to an MC cartridge. The SX-D7000 was available in 1980 and 1981 at a $800 suggested list price.

And you can buy a SX-D7000 manual here:
