Cgs synth

A couple of clues:

1) You only need to do the modifications specific to your version of the

board. Ver 0.2 modifications do not need doing.

2) Decoupling capacitors are to keep the power rails stable. These parts are

already on the PCB. You do not need to do anything extra.-Great, the capacitors are already in then.



I don't have any V0.4 left, so hopefully someone else can answer the questions.
-Doh!-One more thing. I don't know what a "bead" is. Is it like a resistor? thanks a lot. (I still have the remaining questions below if anyone can help.)steve

the 47uF capacitor. Make the cut near the capacitor."]

>I can't find anywhere that pin 5 of the TL072 is connected to the 47uF

capacitor. Pin 5 seems to be connected to a pad that is supposed to be a

jumper wire. And that's another thing, in the Modifications for version 0.2

it says to remove the jumper between pin 5 and the WS Trim. Should I still

not put in the jumper or should I go ahead and do it since this is a later

version.
