Design a switched-resistor volume control. Choose series, shunt or ladder topology; set A (log), B (linear) or custom dB-per-step taper; pick an E-series. Get the full schematic, a step-by-step dB table and a shopping parts list -per channel, so double for stereo.

How to use
Three taper modes — A (log), B (linear), or custom dB-per-step.
What it's for
Build a switched-resistor volume control of the kind used in high-end amplifiers.
You enter
Total resistance, number of steps, topology (series / shunt / ladder), taper, and the E-series for real parts.
You get
The full schematic and a step table — attenuation in dB and resistor value at every position.
A parts list to take shopping (per channel — double for stereo), plus total attenuation range and resistor count.
