Goldpoint 100k stepped attenuator populated with Dale RN55 resistors. It's 24 steps. $140, price includes shipping to CONUS.

I believe the Stepped attenuators, like L-pads, use a series and a shunt resistor at each position. The pair form a voltage divider which keeps the input resistance constant (in this case, 100kR) while varying the amount of the source voltage applied to the downstream load.
I could be mistaken. I'm not sure.

FYI: I'm using a 100k Gold point stepped attenuator and a switch and I can attest to their quality. Been using mine everyday or at least ten years. Still working like the day I installed them.
I have a need for a 4 gang stepped volume attenuator. 2 gangs are 53.38K and 2 gangs are 3K. Ideas on how I may achieve this?
To pick your knowledge, how can I test the log plot on a potentiometer? I imagine a chart defining dbv in vs dbv out, with the ability to rotate the shaft to full range and then plot.
