[sdiy] Aries modular schematics detail

[Terje Winther]

Hi,
A friend of mine and me are looking into the Aries modules. Many of them
should be easy to clone, but we run into two questions with the schematics:

The module no. 314 VCF has a part called U6 marked "Exponential converter".
Anyone with information on this?

Also, the module 329 Flanger has a part called PD10 with no other marking.

All types of suggestions appreciated.
