Pioneer - SX-D5000 Tuner

Pioneer SX-D5000 – Quartz Synthesized Stereo Receiver (1980)

Pioneer SX-D5000 quartz-synthesized stereo receiver, manufactured in Japan in October 1980 (serial number AJ8400607S).

An authentic monster from Pioneer’s D series…

Transitional model from the early 80s, one of the first Pioneer D-series receivers with a quartz PLL digital tuner. Represents the shift from the classic analog design of the 70s to the digital aesthetics of the new decade. Limited production and hard to find in good condition, especially with the silver front panel well preserved.

Technical specifications

• Net weight: 16.2 kg
• Power supply: 220/240 V ~ 50/60 Hz with voltage selector (European/export version)
• Speaker impedance: A or B = 8 Ω; A+B = 16-32 Ω
• Tuner: Quartz PLL digital synthesizer (FM 88-108 MHz / AM 535-1605 kHz)
• 6 “Station Call” memories (FM + AM)
• AM step selector 9 kHz / 10 kHz

• Digital tuning and signal display
• Full connections: Phono MM, Aux, Tape 1/2, Adaptor, Pre Out / Power Amp In, FM 75 Ω / AM 300 Ω antennas

Condition
The unit is complete and in good working order.
The digital displays illuminate correctly, the FLUROSCAN power meters function, the tuner locks onto stereo (visible example at 92.20 MHz FM) and the Station Call indicators operate normally.
AM bar antenna (ball-joint) included.
Cosmétically it shows the usual wear of over 45 years: scratches and marks on the silver front panel, some residual dust, tape residue on the bass slider and light wear on buttons and knobs. The chassis and rear show signs of use, but the whole unit is complete and operational.

Notes
Limited production model, considered relatively rare within the Pioneer lineup of the era. Silver front panels are prone to damage, so specimens in this conservation state are not common.
Receiver with the characteristic warm, low-distortion non-switching stage, solid quartz tuner and a very representative early-80s aesthetic.
