This lot consists of six large tubes, two smaller ones, a socket? and a metal tube (RCA 6AG7). I know nothing about them. I found them in my garage when I moved here 25 years ago and just left them there. last week I was cleaning out the garage and thought maybe somebody may want them as a collectible. I do not know if they work. The sharp tip on one of the small glass tubes is broken.  Free shipping in the Continental USA. Others use zip or country code.
