The Clockwork Torque
Where Swiss designers pursued suspended silence, Dual chased mechanical drive. Originating in Black Forest clockwork tradition, these German machines coupled continuous-pole induction motors to heavy cast platters through high-friction idler wheels, delivering explosive rhythmic propulsion.
Clockwork Cam & Rim-Drive Geometry
The Dual idler mechanism unites massive rotational inertia with low-friction tonearm tracking. A stepped brass pulley feeds motor torque directly into the inner platter rim, while an under-chassis grooved cam synchronizes automatic cycling.
The Four Classic Decks
From compact idler brawlers to the world's first coreless direct-drive motor. Click any deck to inspect forensic specifications and restoration data.
Dual 1019
The little giant of St. Georgen. Packs a massive 3.4kg non-magnetic platter onto a compact ten-inch chassis, delivering bass weight and rhythmic drive that out-muscles modern decks.
Dual 1219
The flagship workhorse that expanded the 1019 engine to a full twelve-inch platter chassis. Introduced the dual-height Mode Selector tonearm base for perfect single-play VTA tracking.
Dual 1229
The pinnacle of Dual idler refinement. Integrated illuminated optical stroboscope viewing window, refined four-point gimbal bearings, and high-torque mechanical grip built for rock and jazz groove dynamics.
Dual 701
The silent revolution. World's first coreless direct-drive electronic motor. The EDS 1000 brushless Hall-sensor motor spins at platter speed with zero cogging and an astonishingly low noise floor.
The Dual Restoration Bench
Black Forest clockwork mechanisms are built like mechanical watches. Addressing these four common service points restores factory operation for another forty years.
Steuerpimpel Clutch Pad Renewal
The vinyl clutch sleeve underneath the main tonearm segment disintegrates over decades. Replacing this tiny friction pad restores full automatic tonearm cueing, lead-in, and auto-return cycling without sticking.
Main Cycle Cam Degreasing
Original factory grease hardens into yellowed glue inside the cam wheel tracks. Flush clean with isopropyl alcohol and re-lubricate with modern lithium-based Shell Alvania grease for effortless mechanical movement.
Idler Tire Perimeter Dressing
A hardened or glazed idler tire causes subtle speed slip and audible rumble. Mount the idler wheel in a low-speed chuck and gently dress the outer edge with 600-grit sandpaper to expose supple virgin rubber.
Induction Motor Bushing Satiation
The continuous-pole motor uses upper and lower sintered bronze spherical bushings. Disassemble the motor clamshell and submerge the bushings in warm turbine oil under vacuum to refill the microscopic bronze pores.
Dual 1019 in The Listening Room
Heavy rim-drive torque produces distinct sonic results in the listening room. Under bench testing with the Shure M75ED Type 2 cartridge, the compact Dual 1019 revealed startling low-frequency punch and rhythmic bite that belt-drive decks absorb.
