Good to hear it's all going smoothly now

Ok, I got my BOM all ready for ordering from Digikey. I still need to source the tubes (I'll be building the 12AU7 or w/e the heck it is version), the sockets, and the power supply. I was wondering if anyone wouldn't mind taking a look at my BOM as it stands now? I'm up to $38 right now and was reaaaly trying to keep it under $50. I don't really wanna skimp on anything that might really matter though. So I'm open to any suggestions. For example, did I choose a crappy pot? I don't know! What about the headphone jack, or RCA jacks? I was pretty much just choosing w/e had the best looking picture, or looked about like what is listed in the original BOM. So please help me headfi!

<edit> Also ,looks like the Mosfets are backordered? Can I get different ones?

Wow that's awesome! YGPM my friend. By the way, did I mention that I'm a soon-to-be-married starving student?

My bad. I'm pretty proud that I'm getting married and I tell anyone who'll listen.

Well, finally it's done. Here's the schematic for the 12AU7 version including the optional parts from the Beezar.com PCB version.

Dsavitsk agreed to have his name on it; obviously the mod had been in his mind before I came around and built it

Alright I thought I could do it but still I'm epic failing at this. Anywhere I look for tubes (12AU7) they seem to be ~$16. I thought these could be had for cheaper? Or maybe its an alternative that can be had for cheaper? Also, i'm trying to find a tube vendor that will also sell me the sockets I need, as I don't want to have to go to another party, and have to pay shipping a third time, for two small components.

Not really - that's sort of the one disadvantage of using 12AU7's. At least for some types, they can be among the most expensive.

Try some 5963's and sockets at Antique Electronic Supply - Antique Electronic Supply. There are some places where you can get them cheaper, but probably not with the sockets, too.

Looks great! I'll try to post it today!

Sweet, it turned out a lot cheaper at the site you linked than at thetubestore.com My total is now under $50!!!! Including tubes! Alls I got left is to think about a chassis. Woot. I think I'll use a breadboard as my common ground, instead of a copper plate. does that defeat the purpose or will it suffice?
