ok, the difficulty with digital pots - if I am understanding the specs:
the smallest is 10k, I'm using a 5k
the number of (programmable ?) steps is 256, yielding a resolution of 39 ohms with a 10k pot
as I presently make adjustments of several ohms, I think this may not work
even running 2 in parallel I'm still at 19 ohms
am I missing the obvious ?
