Today's layout is Brian's take on the PT2399-based delay. It's similar to many other PT delays, but is it's own beast. It can do anything from simple slapback delay to up to around 500 milliseconds of delay. I've laid it out for board mounted pots and it would be a snug fit, but i'll fit in a 1590B (especially if you use low profile jacks).

- Regulator left of the 1N4001 near the top: no value on the populated board, the wiring diagram prints 7805 (a TO-92 outline, so in practice a 78L05)
