Moog Prodigy clone DIY

[savagedog]

It really must be very, very, very difficult to type "moog prodigy service manual" into Google and click one of the search results .

May i had one downloaded and it was the wrong one? so i asked for the right one? And if someone allready did load the right one so its wrong to ask for the link?

But thanx for the link

The last letter (A,B,C,D) is just which part of the chip is meant if there is more than one.
So U1A, U1B, U1C, U1D are all in chip U1.

As U1 is (AFAIR) an TL074 (or TL084) it has 14 Pins and that does look like this:

  1 1 1 1 1 
  4 3 2 1 0 9 8 
+-o-o-o-o-o-o-o-+
>               |
+-o-o-o-o-o-o-o-+
  1 2 3 4 5 6 7

Top view, watch out for the pin 1 mark... 
(here left or bottom left)
