[sdiy] All Electronics Trip

Seems I stand corrected.
The run of the mill Radiohm and Piher pots I get here  are A=lin.
Omeg follows this rule as well.
However it seems these are the exceptions and most manufactures mark as
A=log.

And then there are the odd cases of some Cliff and Bourns pots where no
A/B mark is present. But either log and lin tapers have a different order
number
or no marking is used on the most common taper for that type pot,
which could either be lin or log...
