I definitely want to see pics of your project!!
I broke down and bought one of the 6418 lots from eBay:
Yesterday I pieced together a BOM from Mouser:
I'm interested in opinions on the upgrades, and I'd be grateful if y'all would double-check my components.
I decided to go with Nichicon Muse Gold for all caps. Output caps upgraded to 1000uf and input caps to 1.0uf WIMAs (an idea from Fred_fred2004 in this thread: http://www.head-fi.org/t/522639/oatley-k272a-build). I also added another pair of 1.0uf WIMAs to use in parallel with the output caps.
I'm a bit frustrated with the L4949 IC, it appears that no one (Mouser, DigiKey, Newark) has it in a dip-8, only in surface mount. I know how to solder and have a good iron, but soldering smd seems to be another level of skill (that I'm not sure I've attained yet).
I'm also unsure what to do about the trim pots since I'm looking to make this a portable amp. Can I eliminate the pots entirely and go with the stereo pot I have in the cart, or do I use the trims AND the stereo pot together? If so, how do I wire them in?
