This is how I wired my pot. Don't forget to ground the metal pot casing too.
Such a nice little amp! ...build another one with some 17EW8's or 12AU7's.
Thanks Beftus, that perfect, and it matches the pic of P. Millet! All my problems resolved!

Show us some pics! I have a 12AU7 version which sounds absolutely wonderful. I like it better than my Hi-Performance Mini³. That's what I would like to have: a headphone amp with the the sound of my 12AU7 and the portability of the Mini³.
Looks good Trower, I really like the look, its "Starving Student" for sure. How about a peek inside ? How much did you spend on the build?
The idea of doing a P2P build of this scares me a little. The idea of troubleshooting a P2P build scares me a lot.

Since the PCBs aren't available any more, I thought I might try doing a protoboard build using the Radio Shack 276-0150 that tangent's cmoy tutorial uses. The first step of my plan was to draw a board layout and post it here for comments; I was hoping to get some advice before I started, however.
Thanks!
- Is this an entirely stupid idea?
- Any recommendations for how to draw the layout (besides pen and paper)? The images on Tangent's site (160k pdf) are nice, although I don't think I need them to be so fancy. I was hoping Eagle would have some protoboard templates, but no luck.
- Are there any parts of the layout were I'd need to allow extra space between components?
Are the 12AU7 like these the cheapest tubes to use? What is the likely hood that within a year one of the tubes will fail? Would it be worth it to get 3 or 4 as spares since the tubes are $5 each and shipping is $8 no matter how many I get?
