I built this power supply for an upcoming Eurorack project (TBA) that will be rack mounted. I used the same Tiptop Audio Zeus Studio Bus supply as the one I put into a skiff some years ago. The project will be a 3U 84hp system with ten modules. It will mount in the front of a 19-inch rack with this supply mounted at the back.

I used painters tape to hold the board in place while I marked the positions of the mounting holes. The board is fastened using nine #6 threaded metal standoffs and 18 #6 x 0.25 inch machine screws. The standoffs are Mouser #534-1922A.

Only three parts were needed, as shown in the above photo. The big toggle switch (Mouser #633-S2A) is way overrated for the voltage and current needs, but I wanted a large bat handle, easy to reach behind the rack cabinet. Power inlet is Mouser #502-721A

The small amount of wiring was simplified by the spring loaded connectors on the Zeus. The Zeus has four ground and two +15V input positions. These can be used to simplify distribution when multiple Zeus Studio Bus supplies are used together.

The inlet, ground, and switch will be on the left side of the rack. This photo is thus inverted from what it will be like when installed. I want to reach the switch at the bottom.
