To my shame, I have to admit that I sought out the
following pic to confirm
the wiring to the Alps pots I received today for the
purposes of mending my
'dog's bowl' attenuator:

Thankfully, the picture confirms what I suspected and was
trying to
remember (specifically Earth on Pin 1 - both channels),
but the labels
read quite clearly signal 'in' and 'out' - does this
actually matter if
the two channels are wired in the same fashion??

(I don't see how it can, but am I missing summat...??)

This is what you're actually doing - or should be. One
channel only shown.

If you swap 1&3 (both channels) the pot will just work in
reverse.

Meaning? Surely log pots need to be the right way round?

I've been a bit bemused by the argument that the value of
the pot doesn't matter much. Too late to argue now.
