Gorgeous, Vintage 70 WPC Pioneer SX-939 Stereo Receiver in Custom Cherry Wood cabinet
This exceptional Japanese-manufactured Pioneer SX-939 AM/FM stereo receiver delivers the warm, rich sound that made the SX series legendary during the golden era of 1970s hi-fi. Originally part of Pioneer’s prestigious SX line, this 70-watt per channel powerhouse has been transformed with stunning custom cherry wood cabinetry crafted by our master woodworker, elevating this already impressive receiver to a true work of art.
This fully serviced receiver features Pioneer’s renowned parallel push-pull OCL power amplifier with less than 0.3% total harmonic distortion, paired with a completely new PLL MPX circuit and frequency linear 4-gang variable capacitor. The unit has undergone our comprehensive Level 2 service protocol, ensuring optimal performance and reliability. While there is some light wear along the top metal lip of the faceplate, this character-adding patina is typical for a 50+ year old component and tells the story of this remarkable receiver’s journey through the decades.
The custom cherry wood cabinet is brand new and absolutely gorgeous, providing a stunning contrast to the classic silver faceplate. The receiver lights up beautifully with its signature illuminated dial, and the sound quality is fantastic with tons of power to drive virtually any speakers.

JVC JR-S201 Receiver – 35 WPC, Japan, SEA EQ, Excellent
Thirty-five watts a channel at 0.01% distortion with a damping factor of 70 — numbers most larger receivers of 1978 could not reach.

Pioneer SX-50 Silver Face Receiver – 50 WPC, Pre-Outs, 1983
Fifty watts a channel into 8 ohms at 0.007% distortion, and — unusually for a receiver this size — pre-out and main-in jacks on the back, so it can feed a subwoofer, take an equalizer in the loop, or hand off to a larger power amp. Introduced in 1983 with switchable CD and TV audio inputs, presets held by three AA cells, and the silver face of the decade that was ending. Graded Very Good.
