Downloadable tube pinout guide

I don't know about you, but I'm constantly having to look up the pinouts of tubes during my builds. Even when wiring common tubes that I have memorized by now, such as the 12ax7, I invariably have one last look at the data sheet just to make sure before the power up. After all, nobody likes 300 volts on their grids.

But here's the problem: In the middle of a build cycle, my shop tends to get a little messy, so data sheets get buried, laptops are upstairs...you know the drill. So I decided to make up a printable, standard-letter sized sheet with all the pinouts for the most-used tubes in amp building. Now I can just tack one sheet to my shop wall for those last-minute sanity checks.

Feel free to click here to download the tube printout guide for use in your shop. You'll need Adobe Reader to open and print it, but I think almost everyone has that these days. I hope it makes your builds go a little bit faster and easier.
