Amperex 3-500zg tubes, matched pair,NEAR NEW!
 

I have a pair of near new(as in only used for a few minutes to test),
Amperex 3-500ZG tubes listed on eBay. As you may know, the Amperex
3-500 graphite tubes are the most expensive available. These are VERY
rugged 3-500 type tubes, and can take appreciable drive. Here's the

I might be open to some equipment trade offers too.
