I'm about to order parts for my first DIY CMoy and I have a few questions before I pull the trigger on my Mouser BOM. I'm going mainly off of the Tangent tutorial along with all of the suggested parts upgrades I've found by searching through the forums and looking the JDS CMoyBB parts list. I'm still left with a few questions though…
Since I am a Grado fan, I want to build my CMoy so it's tailored more or less to properly pushing them. I'm using a ~4.7k ohm resistor in R3 for a gain of 3.
1. Since I'm using only 32 ohm headphones am I ok with using only a single 9V battery or should I use two?
2. Will this parts list work well for the JRC4556 opamp? I'll probably try some other op amps at a later point, but for now I like how cheap this one is and I hear good things about this paired with Grado headphones.
3. After reading the virtual ground article on Tangent I've decided to use the TLE2426 rail splitter. If I'm tailoring this for my Grados, should I go with two of them or will the single splitter be ok with the JRC4556?
4. Are there any other points I should consider for custom tailoring this first CMoy or any parts that I need to add? I think there's enough here to do a complete build on some perf board I'll grab at Radio Shack.
While this is largely just a test build, if it turns out well enough I will try to stuff it into a tin and use it primarily with my iPod classic + LOD.
Thanks in advance!
