Today, I worked on the case. This is my current case for the prototype. This will NOT be the case used for the "Tapers Edition" preamp. Instead, it will be wider to accomodate 2 channels and 4 full-size XLR jacks, but shorter in height.
For now, I just want to get this prototype in a case.
The case is extruded aluminum with PCB guiderails. It has good shielding characteristics. In addition, I add some support bolts to the PCB. I want to make sure the PCB is securely fastened to the case.
I laid out the parts and dimensions, and used it to generate the necessary Gcode files for my CNC machine. Went down to the garage and start miling. In a minute or two, it's done.
Test fit... and all the holes align perfectly.
Attach the nuts, looks good.
Start mounting the VU meter, attaching the XLR jacks, and knobs.
Rear view of the XLR jacks... perfect holes.
And it's done. Single channel prototype.
I'll play with this for a few days, just to make sure everything is alright. Then, I'll loan this single-channel pre to you guys. If I get good feedback from this, I'll proceed forward and make the 2-ch version with all the doodads (i.e. features) you guys requested.
