Okay, two months since my last post -time to dive deeper into the enclosure.
I spent the past two weeks designing, ordering materials, and milling all the necessary holes. After breaking two milling bits in the process, here’s the result!
The upper panel features over 30 screw holes for the amp boards and power supply. The transformer is planned to be mounted in the center using an M8 bolt, along with an isolated cover. Most of the screw holes are chamfered (using a chamfer milling bit). The square holes are designed for the transformer wires to pass through. The tapping work was manually done.
Here’s the hole for the volume pot. The pot can be installed upside down to provide more clearance. I used an end milling bit, which resulted in this textured finish.
The side panel will house the 10M90S without heatsinks. The plan is to transfer the heat directly to the enclosure. The enclosure dimensions are 430 x 80 x 330mm with an 8mm thickness.
Two XLR input holes.
Hole for the EMI AC inlet socket.
I’ve realized that I might need a more professional CNC milling machine, but my garage just doesn’t have the space for such a large machine. Milling is really fun and incredibly satisfying.😆 How about going even further next, let`s say a fully CNC block enclosure (I am planning it right now).
