Admiral 6CB6 Tube, Made in USA

Admiral 6CB6 tube made in USA, tested good.  

This tube has been tested on a Triplett tester for emissions, leaks, shorts, etc. and tested good.

I am listing this tube as used, though it may actually be new. This is from a huge batch of tubes that were mostly new, but some had been put into white boxes because their original boxes had lost their rigidity. So expect a used tube, and if it turns out to be new, it's a bonus for you.
