Dual 721

2-Speed Direct-drive turntable with pitch control and illuminated strobe

Dual 721

Description

The Dual 721 is a fully automatic, single play, direct drive successor to the quietest turntable ever made.

Independent test reports on the electronic direct-drive Dual 701 were extraordinary. Their results are still pertinent since the CS 721 has the same drive system.

Hirsch-Houck Labs found the wow level 'essentially at the residual level of our test record', and the Feldman Lab report in FM Guide was able to detect 'no flutter whatsoever'.

The CS 721 tonearm has a number of new developments that contribute significantly to fine tracking performance.

Most notable of these is the tonearm base which has a vernier height adjustment for setting the tonearm parallel to the record with any size cartridge.

This eliminates the added mass of cartridge spacers otherwise needed to achieve precise vertical tracking angle. It also makes cartridge mounting and interchange more convenient.

I bought my player around 1974?. About a Year ago the cartridge holder broke and I put the turntable away. I bought the holder and a needle and put my turntable back together again, and am ready to tranfer my records to cd. But my arm lifts up and then down. I can't get it to go to the record. Any ideas

I have had that problem with another automatic player. ait needed some oil at a bearing of a arm. The old oil has been hard and the arm was allmost fastend.
