Many tubes transmitting and Miniatures: I am selling loads of vacuum tubes, both transmitting and miniatures and in between. Some new in box and others not. None have been tested. Examine the photos to see what you are buying. No picking or choosing. Buyer takes all! The tubes are some many ham estates that my late husband (WK9Q) bought over the years. $1,000.00 takes all. Local pick only.
