NE570N Chip that is now obsolete.... apparently. But Doctor Tweek has scored a hundred of these wonderfully useful items. Better noise specs (far better) than the NE571 and with a greater voltage supply tolerance (6v thu to 24v), although a bit of a moot point if powering from a 9v supply. Just more headroom. Get building that compressor - or add this to your PT2399 build to make things quiet and polished.
Great price - genuine item, not a re-pro. DIL Package. Date of Manufacture: May 1996
