GrubDAC as a cable dac in the aforementioned 1551HTBU.

Stupidly Bright White LED shining through the case:
To do this you need to:
- Cut two corners off the board.
- Choose short caps for C9 and C10
- Depending upon how short of caps you chose for C9 and C10, you may need to remove the 2 circuit board "bosses" in the case to get the board closer to the bottom. In my case I actually used a drill to remove them
- If you had to remove the bosses, there is some "supports" for the board on the two pillers that the lid screws into that need to be removed. An Xacto worked well on these.
- Drill holes for the two screws (1/8)" and the end grommets (1/4")
- Use 4/40 nylon screws to avoid scratching anything the DAC sits on and use washers on the inside to ensure the DAC doesn't sit on the bottom of the case.
- The other item of note is the USB drain wire. It will not fit in the Ground Holes. What I did was take the drain and the ground from the USB cable and put them in one of the holes of the USB connecter and then jumpered that to the GND positions (as the USB mounting holes are not connected to anything)
For this one, I used United Chemi-con polymer caps (PS-A and PS-E). They have quite large capacitance for the size
The big pain about this is trying to get the DAC into the case after you've soldered the wires on. It is a PITA, but it can happen. I like have the translucent case with the LED shining through as an effect.
I suspect that you should be able to do fit a Bantam in this same Hammond case. I did a search, but didn't find anybody doing it (but I might have searched wrong
).
