5106 to SAD512 mod

[gfxbss]

Hey there,

I have a DOD Performer 575 with the 5106 delay chip dead.  That being said, I have a SAD512 in my parts bin(also another 575 w/ 5106 that works) and want to mod it to take the 512.  Then make some recordings and compare the pedals for differences......

The problem is, I am not experienced enough to understand how to properly bias the pedal for the 512 and was hoping some of you guys could help.

Schem for the 575 can be found at http://www.mif.pg.gda.pl/homepages/tom/files/dod575.jpg

Any help would be appreciated.
