Dual 506 Belt-Drive Turntable in Walnut Cabinet – Serviced

Dual 506 Belt-Drive Turntable in Walnut Cabinet – Serviced, Upgraded Cables, ADC Cartridge

Rediscover your vinyl collection with this stunning Dual 506, a “Made in Germany” classic housed in its original premium Walnut-finish cabinet. While many turntables from this era (1979-1981) switched to plastic plinths, this deluxe version retains the warm, furniture-grade aesthetic that defines vintage audio. Combined with Dual’s Ultra Low Mass (ULM) tonearm and a host of upgrades, it delivers both visual elegance and audiophile performance. This unit has been serviced and restored, featuring premium interconnects and a classic ADC cartridge for a rich, warm analog sound.

Serviced & Upgraded:
We have treated this Dual to a comprehensive service to ensure reliable performance:

New Drive Belt: A brand new, correct-tension belt has been installed for accurate speed and quick startup.

Cable Upgrade: The original thin factory cables have been replaced with high-quality shielded RCA interconnects. These offer significantly better signal transfer and noise rejection than the stock wiring.

Cartridge Setup: Fitted with a vintage ADC QLM Series cartridge. Known for its rich, “broadcast-style” warmth, this cartridge is a fantastic match for classic rock and jazz.

Level One Service: This unit has undergone our Level One service and testing which should ensure many more years of reliable performance ahead.

German Engineering & ULM Technology:
The 506 features Dual’s proprietary ULM tonearm, a rigid yet lightweight aluminum alloy tube designed specifically to track warped records better than heavy vintage arms. The Walnut-finish wooden plinth provides not just classic looks but also superior mass compared to the standard plastic bases, helping to dampen resonance for clearer sound.

Features:

Premium Walnut Cabinet: The rare and desirable original wood-finish plinth, adding a touch of mid-century modern class to your setup.

Semi-Automatic Operation: Features “Auto-Lift and Stop”—at the end of the record, the tonearm lifts gently and the motor shuts off.

Pitch Control: Fine-tune the speed with the “Vario-Pulley” system.

Illuminated Strobe: Built-in orange strobe light allows for instant visual speed verification.

Suspension: Floating sub-chassis isolates the platter and arm from external vibrations.
