Description

I collected up a bunch of these 7289 tubes for 1296 power amps and never used them. I am told these are same as 3CX100AS type (is that so?). Here are three I pulled at random from my stash, this is an experiment to see if anyone wants these. I have not tested them, but if you can tell me how to "gin up" the setting for my Hickok 6000 tube tester, I will give it a try! Maybe you have an amp and want some spares! You get all three for one price. I will wrap them carefully. Have fun.
