Hey guys. I'm thinking of building the millet hybrid or the starving student tube amp. I can find places that have parts list and directions, but i just can't find where the PCB boards for these are being sold. Does anyone know where i could find one?
Also, should i buy a case or attempt to use a metal box lying around.
Thanks guys!

I believe beezar.com is the only distributor of the PCB's.

Thanks. Decided to try P2P since it seemed simple enough. I have another question though. Would any 7 pin tube socket work for the starving student? The parts list says SKT 7 M1, and i'm not sure what the M1 means. Also, what tubes should i use? Would the 19J6 be a good start?

No more PCB's are available.
 
Unless you find some 19J6 sitting around, your going to need to go 9 pin and 17EW8 or similar.
 
This is the schematic for the 9 pin version.

The only real substitution from the original parts list (besides any of the optional stuff.) is the 390omh resistors in R2 & R8.
 
This is the current parts list I have on order for mine.  I subbed 63volts 470uF 20% general caps for the audio ones suggested because they were back orderd.  Not saying it's all correct, but I had a hell of a time figuring out what I needed and what I didn't from the 370 page thread

hmm thanks for the info. I've seen 19J6 tubes on sale at ebay though. Are those legit?

I'm sure they are. There's nothing special about the 19J6, though - the only reason Pete Millett used them in his original design is because at the time they were dirt cheap and plentiful (~$2 apiece). Now, since you're doing P2P anyway, you may as well swap out a few parts for the 12AU7, 17EW8, or 12SR7 versions.

Ah I see. Then for those 12AU7 tubes, what kind of a socket do you need? Sorry I'm a novice at this DIY stuff. Think i can figure out the schematics though

Yes, the 12AU7 has nine pins, so requires a nine pin socket (aka noval). You'd likely want a chassis mount socket, not PCB mount.
