|Elliott Sound Products||Project 26A - PT2399 Digital Delay|
The layout for the digital delay is unchanged from the published project. The PCB is supplied with the PT2399 delay IC, as many people will find these irksome to obtain in one-off quantities. The delay is inexpensive and easy to build. Like all ESP projects, it does require good soldering skills though.
The layout includes provision for delay time and repeat controls (8mm pots can me mounted on-board). The constructor can choose whether to use the full filters shown in the data sheet, or a minimalist arrangement that works well with short delays.
Note that there is a very small error on the board, which requires no track cuts or links. The fix is explained in the construction article.
