[Amps] [A bit OT] PEP reading for a Bird

[QSKguy at aol.com]

Hi all.
I would like to read PEP on my Bird 43.
I found some kits on the web :

(http://home.att.net/~hi-res/Kits/PDC-1/pdc-1.html) 
 
All of these kit seem to have the same components, they probably use the  
same schematic. 
These kits are not really expensive but ordering from France is always  
difficult.
So the question is : do you now where I can find this schematic ?
The only one I found is the K0XP one but I want to continue using my  
different bird plugs.
Thanks a lot.
