Have you checked that the actual circuit-board trace is working at the
2.2 cap? When I built mine (which I was never able to get to fully work,
alas), I found the traces to be very delicate and easily destroyed by
only a couple of resolders, that is, they'd break where the trace meets
a mount point. So try a patch or two - that may be it.
