TDX Stereo Card - Prototype Complete. 25th November * Update*. Prototype was completed tonight. Didn't take long to solder together and all worked (kinda).

TDX Stereo Sound Card - Breadboard Complete. Bread Board is complete. Surprisingly all worked (well had an initial issue where i wasn't providing 5 and -5 volts properly to the board), bit of hiss in the background, but suspect this is because its on a breadboard. 517-3181 - TL084I quad 3MHz 13V/uS op amp, DIP14.
