Vintage Synth Repair

I performed the resistor modification on the filter of my
Arp Avatar and got... no souind at all.  The values of the
resistors removed were correctly identified according to the info I 
have and the ones I put in were also the right ones. When I put 
resistors of the original values back in it worked fine. Any 
suggestions ?
      That problem aside does anyone have in depth instructions on
how to put patch points on an Avatar ?

Ditto that, I'd *love* to find out more about putting in C.M.S. Style 
patchpoints, especially if Phil Scirroco is no longer doing them 
(which I recall hearing he might not be.)

I remember once on the AH list when people were talking about reverse 
engineering the C.M.S. patchpoints mod.  I wonder if it's as simple 
as finding the right poit, cutting traces & running wires out to 
normalled 1/8" jacks, or coud there be more complex buffering or 
something that Phil does...

Would be great to cross patch between the Avatar and the 'ol 
Keyboardless 2-voice.
