Hi

I'm no electrical engineer, but I had assumed that the 4 VC circuits on the PCB should effectively be the same? I've noticed that the values for R15 and R16 don't follow the pattern of all the other resistors and appear to be switched?

Apologies if this is correct.

You had me worried there for a minute. Thankfully, the Builder's Guide and PCB are both correct. The locations of those two components on the board are different to the other three channels and, since the numbering on the boards works in a logical order, the numbers appear to be swapped.

If you build it as shown in the parts list it should all work as it should.

Oh, my apologies. My simple brain works on pattern recognition, rather than looking at the pcb and identifying that the input for Release comes in on a different pin, compared to A, D and S.

I should have known not to question the master we're not worthy

Motto: Think first , then email.... d'oh!
