Glasshouse / NOS Audio Note 2-pole 23-way switch / Mono Ladder Stepped Attenuator
As discussed in our Blog - Choosing The Right Stepped Attenuator For You, the ladder version of stepped attenuators gives the best performance. However, they are more expensive and larger, as they require an extra switch wafer per channel compared to the alternative. This is the lowest-cost mono ladder that we stock, using the NOS Audio Note 2-pole 23-way switch.
We offer 15 resistor types to choose from for this kit.
Dimensions
Shaft: 6mm diameter x 13mm length
Bush: 10mm diameter x 12mm length
Body, including resistors fitted (internal part): 45mm x 52mm (oval shaped) x 35mm height
The front of the switch has a "non-turn" metal lug measuring 3.5mm in diameter by 5mm in length that protrudes through the front panel, so provision is needed. If not required, this can be removed with cutters. If not, a 3.5mm diameter hole 13.5mm from the centre hole of the shaft is required.
Due to the range of values for the Audio Note resistors, we can only supply the 50K, 100K, and 250K options. For the Takman Metal resistors, we can only supply the 20K, 25K, and 50K versions.
