Nice vintage Pioner 2 or 4 channel receiver model number QX-4000. In good working condition and good cosmetic condition. It has a little scratch on the top of the faceplate but it is not that noticeable. All lights appear to work and the unit appears to have had little use.
Here are specs of unit:
Power output: 10W/ch into 8Ω (quadraphonic)
Frequency response: 10Hz to 100kHz
Total harmonic distortion: 1%
Damping factor: 40
Input sensitivity: 2.3mV (MM), 180mV (line)
Output: 200mV (line), 35mV (DIN)
Speaker load impedance: 8Ω (minimum)
Price: USD $349 (1974)
The unit seems to be missing the speaker clips from the back (?) but should be able to accommodate a thick gauge wire. $100 plus $40 shipping in the US.
