Receiver is in very good cosmetic condition except one knob is not original on the bass control. Unit has been serviced and at time of listing all is working. The bass control knob is not original. On the selector area all the decals are missing as to source. Starting left to right: Phono,FM,AM, Aux. (4 total sources). See picture that explains source locations. I have listed for parts or repair since this unit is vintage and when you receive it something may not work. Most of my items will arrive working but no returns. This is an excellent bargain compared to other quad receivers. Fisher stopped their tube products and began solid state but never could make classic solid state like their tube gear. this receiver is from 1974 with 30w/ch into 8ohms.
