I'll see if it works tomorrow.

I'll connect the inside bar stock to a piece of bar stock outside the box via screws. The screws won't touch the plastic with some clearance. I'll also put nuts where there is exposed thread to increase mass. I may be able to steal a half hour tonight to do it. A picture and all that...

I left the DCAO in the plastic box on all day today. The box gets a little warm. The heat sink gets hot. I can only touch it for a second or so. I will modify the heat sink. I have another piece of flat bar stock. I'm going to drill a couple of holes through the original heat sink, the box and the n...

Is that small one inside a sealed plastic box? If so it might be a good idea to add some air vents on top and bottom to allow convection cooling to exchange the hot inside air with cooler room air. The heat sink just helps transfer the heat from the device to the nearby air, but plastic is a poor t...

Very nice! How does it sound? It sounds good to me. Since I don't do a lot of headphone listening I don't have anything to compare it to. I could bring the shop one home and try it next to my NAD. I wasn't using headphones at the studio before. I'd like to try a pair as line drivers. I'd have more ...

I made two different headphone amps. One for the shop and one for the studio. Below is the one for the shop. http://www.saltmastering.com/DCAO/DCAO_Shop-1.jpg http://www.saltmastering.com/DCAO/DCAO_Shop-2.jpg This is the one for the studio. I ended up ordering the fancy TKD pots. I have to send them...

I finally got this up and running. I'd like to put it in a 1RU case. I was hoping the rotary switches would work because the only other pots I have that will fit in 1RU are PEC's. The accuracy sucks so I can't use them. The rotary switches unfortunately won't work. There isn't enough range. I have f...

I found this earlier thread: http://www.proaudiodesignforum.com/forum/php/viewtopic.php?f=6&t=497 Ah, good thread. Like I said, I'm not a big fan of headphones. That's how I missed it. Edit: That's a fantastic thread. Thanks Ricardo. It occurs to me that headphones would be a valuable addition ...

For headphones I would build it with 10-33R. I use 33R for the MDR-7506 and like it. I've also tried 0R and can't say which one is right but there's something different in the low end and I prefer having the current limiting. I'm having a little trouble understanding what governs the choice of buil...

The only schematic is this one: http://www.ka-electronics.com/images/jpg/DCAO_173_DRV134_Schematic_Large.JPG I never drew one featuring both channels because I'm lazy. I was talking more about the tracking circuit for use with the 1646. I don't plan on using a 1646 but I don't think I've ever knowi...
