Toshiba SR-510

Toshiba SR-510E

October   1 9 7 4 october 1974

Pretty and well-remembered turntable with high-end technology and enduring design.

As can be seen from the image below, speed control is with a patterned transparent disc monitored by a CdS photo cell which drives voltage changes to correct speed (if necessary). Very elegant.

The SR-510 (510E in Japan ?) was delivered with a stock tonearm, a dedicated electret condenser cartridge which allowed CD-4 records to be played properly and an optional SZ-200 equalizer (predecessor of the SZ-1000) powering said cartridge or letting the signal pass through if a normal moving-magnet cart was used.

Export versions seem to have a slightly different tonearm with two added tonearm controls.

Specs-wise not an SX-8000 II but ten years separate the two. And quite a few thousand ¥.

A real SR-510 here.
