Servo-Controlled Direct-Drive Turntable (1975-1978)
Fitted with a universal S-shaped tonearm
Models DP-790 and DP-790W are high performance record players from the Denon hi-fi component series, each consisting of a servo controlled direct drive turntable and a universal tonearm mounted on a wooden cabinet.
They differ only in cabinet colour; a Japanese SEN-grain cabinet is used for the DP-790 and a walnut grain for the DP-790W.
Except for the colour, these two models are identical in specifications and operation.
Denon has devised a special elastic material of just the right viscosity, which is placed between the cabinet and the base of the tonearm, to isolate the tonearm from vibrations through the cabinet.
In this and other ways, such as using high quality insulating materials, and inserting reinforcing materials in the cabinet, great care has been taken to prevent howling.
