<p>hello again<br />
building was quite easy(what a pdf!),and testing quite another thing..<br />
C5 is kind of funny one and caused some misbehavior of the circuit(great work)and specially the input(no or faint signal).<br />
so i desoldered, flipped and resoldered it until it was like the printing on the pcb said: square plus,round minus.<br />
e voilà : we have input and  everything..and the w.s.g still makes sense...<br />
yipi!<br />
and sorry for all this fuzz
</p>
