searching for delay shematic

[LiquidSteel]

Hi at all

Once i found a great simple delay shematic with the Cmos 4001. I lost the schematic ... now i'm searching, but i haven't find it yet. Can anybody help me with a simple schematic, but not with the PT80 and AD3208. I also have seen a delay schematic in this forum, only containing oamps, resistors, caps.
It would be great if anybody have s delay schematic with Cmos.

I've got a schematic for a 4016 echo. Send me a PM with a mailadress if you want it.

Wow... I'd like one with a 4001 too, please. I'v'e been thinking about a delay pedal but the chips aren't too available here.

On the other hand, I just found a 4016 from the local internet store. Is the CD4016 it, right?

A 4001 is simply a quad NAND gate. Its a digital logic chip cannot be used to delay audio. You could use one as part of a clock generator, but you could also use and CMOS gate in the same location.

The 4016 is simply a quad SPST switch. This chip is not able to delay audio either.

To make a delay you need a BBD or a specialized delay chip like the PT2399.
