This is a prototype of a Doepfer-compatible synth module case. It is created in curly maple and drilled precisely to mount the hardware provided by Doepfer in their A-100 kit.

We started the project using the Doepfer dimensions and also having in hand an actual A-100 kit so that we could check our work at each stage. The back of the case is drilled for the proper fit of the power buses and power supply. The template for drilling the holes was precision machined on a digital readout milling machine. The rails in the Doepfer A-100 kit allow you to place as many 3mm nuts as needed for total flexibility in mounting your module faceplates. Doepfer provides enough of these nuts in their kit for any conceivable configuration of synth modules.

In celebration of our new venture, we hand picked some extraordinary curly maple. The parts of the case are joined by "biscuit" joints. The case was finished with clear lacquer. If you purchase the Doepfer A-100 kit, you will have the following tasks.

• Mount the rails using eight 5mm self tapping screws (provided)
• Mount the two power busses with 3mm standoffs (not provided)
• Mount the power supply with 3mm standoffs (parts of the A-100 kit)  
• Connect ground wires (provided) to the power supply
• Cut and solder transformer wire to the power supply (parts of the A-100 kit) .

Below is a schematic of the synth module case. The critical dimensions are in millimeters since they were taken directly from the Doepfer instruction manual.
