Sony Walkman DD2 playing Iron Maiden - The Trooper

The Sony Walkman DD2 is a portable compact cassette player from the 80's The WM-DD2 was introduced in 1984, and appeared to be a WM-DD that was available in same colors and had the addition of Dolby B noise reduction. In marketing terms this is exactly what it was, though technically the change was far from trivial. The innovation that made this change possible was the introduction of miniature Dolby ICs that could run directly from the 3V battery supply without the need for a DC-DC converter (as had had to be employed in the WM-7, for example). Even with these devices the changes made between the WM-DD and the WM-DD2 were far reaching and only possible because the printed circuit board was made with track work on both sides.
