And the master slider pot has failed (Chinese so assume unavailable).
Long but tiny cross section stereo 2x 10K log pot. Found a larger one

there maybe enough space and can be screwed onto/under/through the top
panel
and wired into the pcb but it is 2x 250K lin of course.
10K and 1K resitors in parallel with each pot, will that be a work around
or
will the characteristic be too "lumpy" on the low end?

I'd be surprised to see this as a suitable solution. Can you swipe a
pot from the last channel or are they different? I've done this in the
past when no alternative was available and the customer knew what to
expect.


Yep , graphing it out the characteristic is hopeless. Matter of opening up
the pot and dabs of silver paint or a graphite compo along the tracks and a
pair of resistors looks necessary to bring it back to something like
functional equivalent.
