Useful source of switched log pots (EG for DAC90A etc)

[Yorkie]

Also note that you can't do an angular advance versus resistance plot with an ohm meter and expect an anti log plot... It has to remembered that it is a voltage divider therefore to get the correct plot it has to be connected to a voltage source across it's two ends and then angular versus voltage can then be read off the slider.

Using an ohm meter from any end to the slider to plot angular versus resistance will always give a linear plot because the resistors are linear....

Ah, of course Lawrence, using and Ohmmeter with no voltage applied is where I ('scuse the pun!), lost the plot when I was trying to use a taper resistor and seemingly failed - see post 12 at this thread:

What surprised me about the Noble and Princess, was how well they performed with such a low component count.
