Hi All

Any chance someone could post a picture of the jumpers required when omitting the buffer please? I don't want to make a gaff and there's loads of lines on the pcb!

Cheers

James

Take a look here.

The picture only shows the jumpers at QN8 and QN13. Remember the 2 jumpers at QN10 and QN12. They have to be placed at the "-" symbol on the PCB.

the manual quotes that we should omit

qn7, qn14, r25, r28.....

yet I see X's on other places as well
qn10,qn2, r26
qn8, qn7, r25
qn13, qn5, r28
qn12, qn6, r27

does this mean all these are omitted as well?

I will make sure we have an updated manual up soon. The only major differences are the omitted buffer and paralleled FETs.
