MXR 118 Analog Delay with PT2399

[DJGlukBH]

If a PT2399 sounds "better" using 15V for you, you'd be among very exalted and rare company.  The PT2399 normally runs off +5V.  I've never seen a schematic using it that did NOT run it from 5V, and the data sheet indicates 5V.

Now, the rest of the M-118 may well like 15V, but the PT2399 sure as hell doesn't.  Use a regulator to drop that 15v down to 5 for the chip.

Mark, you're right!
Read the 2399 datasheet - 5V indeed! I'm sorry being a bit stupid...

No problem.  All too easy to forget that some circuits can include separate little universes, running off other supply voltages.
