Glasshouse / Elma 1-pole 47-way JUMBO switch / Mono Shunt Stepped Attenuator
Seeing the need for a dedicated shunt version of Elma`s 47, we worked closely with Elma to create a PCB that was not only a dedicated shunt design but could fit the larger 1W resistors. The Elma A47 Jumbo 1-pole 47-step mono attenuator offers great control over your volume sweep and an amazing performance. The resistor values we provide are 1dB steps.
The build is trickier than the 23 and 24-step. Finer soldering is needed, and a lot more soldering is required, with around 92 joins per switch.
We offer the option to choose from 19 different resistor types for this kit.
