For Sale Homebrew Elma 10K Quad Stepped Attenuator – 24 position, series.

Things you have for sale.
The switch is an Elma four-wafer bought from Don Audio. All resistors are Susumu thin film 0805 SMD 0.5% 25PPM, except for R1, which is 0.1%. The switch wafers are made for through-hole resistors, so the SMD resistors have been soldered across the circular pads. Solder is Cardas quad eutectic. The audio taper is taken from a resistor list to be found on the Goldpoint website. Included is a spare resistor of each value.


Please note that the switch bushing is of the new kind. It has two flats and is intended to be inserted into an appropriate panel opening to constrain the device from rotating. There isn’t the familiar tag that slots into a hole in the panel as in older types. The shaft has been cut and drilled (not very well) to accommodate a coupling (included). Never hooked up to any circuit.


€80 incl. postage to UK and EU only.


PayPal preferred.
