Vacuum Tubes Galore

You into vintage TV vacuum tubes in their original boxes? Us, too. We’ve got so many of them, in so many types and sizes, we’ll send you (5) different per order. It's a crap shoot of a deal though. Normally special orders don't upset us, but this time we’re not BK. Sorry, no special requests. We’ll close our eyes, reach into the bin and pull out the first (5) assorted we can get our hands around. We’ve got an eclectic mix of electronic and radionic tubes from brands like RCA, Slyvania, Raytheon, Standard Brand, Philco, Westinghouse, GE, Tung-Sol and Lindal. And they all look super-cool. Some are super expensive and some are run of the mill. These are new old stock. Great Ebay items! (Multiple orders in a short time may result in same assortment.)

Step On It

Perfect for hands-on hobbyists. Foot-pedal speed controls free up your paws to do the real work. This one's for 120VAC devices, and ideal for machines using approx 200W or 1.6A or less. Measures 5" x 3" x 2-1/4" tall, with a 6-foot cord that plugs into the wall and a 2-foot grounded female plug for your sewing machine, rotary tool, scroll saw, or, if you really make a lot of banana Daiquiris, blender.

Light On A Cord

You've seen cords on lights—pull the cord, turn on the ceiling light—right? Well, this is the reverse. Tie the cord onto something on the ceiling, pull the bulb on the bottom and it lights up. Seems backwards, because it is, but it somehow makes sense when you want the light on the end of the rope, not on the ceiling, and don't you think you've been doing things right-side-up for long enough? Bulb is 40 lumens, cool white for indoors, and runs on (3) “AAA” batteries that the manufacturer didn't include.

Electrodes-R-Us

Okay, they’re just strips of metal, but CJ says one of each and a grapefruit will get you at least a “C” at the science fair. The copper electrode is 100mm long x 18mm wide  x .8mm thick (3.94" x .7" x .041”). The zinc electrode is 4” long x 3/4” wide x .027” thick and stamped “ZN”. And both of them are awfully useful for crafters and jewelry makers, too.
