At last online on TVK with a fair image !

The original of quite a few rebadges, the DA-01 CD player shared with the Akai CD-D1 version of it the Philips D/A and digital filter scheme : TDA-1540 and SAA-7020 with the same majority of surrounding Toshiba ICs.
Since the laser in the big DA-910 came from Sharp, it is likely the one in the DA-01 was sourced alike.

And like many other 1st generation CD players, the DA-01 did benefit from a dual d/a system. The DA-01 was originally planned to be all-black in colour.

These images come from the original 1983 USA 4-page leaflet dedicated to the DA-01 which was printed by and © by... Cybernet ;-)
