Super vintage Pioneer stereo Recevier. Model SX-535. The unit has been serviced by an enthusiastic professional. Completely recaped the Audio Output Stage with Japanese Audio Grade Capacitors from Japan. Replaced 9 Capacitors, 10 Transistors and 3 Bulbs. I was able to get 25 Watts x 2 @ 8 ohms before clipping with 1 KHz sinewave input source. The unit service to last more decades and this comes to a cost if you looking for a wonderful pro serviced unit this chance might be yours. I have attached all the pictures of the parts that have recapped and serviced. All pictures are original of this unit and part of description so what you see is what you get !
