    Looks a little light duty to me. I'd imagine it'll cost easily $75-150 in quality parts, plus a ton of labor. For $125 or so you can find a very nice transconductance tester from B&K or Lafayette or Heathkit if you wait around to find one.

    I use a baby Lafayette emission tester I got for $12. Muchxs apparently started on the same one hahaha.

    Either get a cheap tester for personal use (a good no-go tester), a Hickok, B&K, or high end Heathkit for selling tubes, or if you want to build your own, get a uTracer. It'll do the same things as a $5k Hickok tube curve tracer. You can sell preamp tubes for top dollar with it.

    Looks simple enough to do with junk box parts.

    This device was designed for an Australian audience where our location unfortunately means exorbitant freight cost for anything of weight imported so the aforementioned vintage testers become an expensive proposition to import. The transformer listed in the schematic is cheap and available here (Au). The other parts are inexpensive. Granted the U-Tracer would be fantastic but would be beyond many builders in construction, operation and cost. I would take this project for what it is, A simple cheap but functional piece of equipment that anyone with amp building experience can handle.

    What an amazingly cool project the uTracer is... never thought I'd see a microcontroller driving a vacuum tube via a Windows GUI!

    Amazing tech. I hope to build a well designed physical implementation of one someday for an engineering project for college credit.

    Check out the project link, I thought I read that there might be a linux port, which means someone has likely compiled it on mac...
