PIONEER QX949 QUAD/STEREO RECEIVER. USED. STANDARD SHIPPING. ADULT SIGNATURE. This unit has been serviced/all inputs tested/LEDs installed. This is a great receiver by Pioneer which debuted during the mid 70’s when four channel was all the rage, although made for four channel this is a fantastic sounding stereo in 2 channel in my opinion better than when it is engaged in 4. This unit has some cosmetic wear to the cabinet/chassis along with one rear channel meter is out [as pictured], but it presents extremely well. This is a great sounding receiver by Pioneer, and it comes with the original packaging which is a great addition to any vintage audio collection.
