This is a like new pair of JJ 300B vacuum tubes. They have been gently used for 7 months in a preamp. Yes, preamp - a Bottlehead BeePre. They test like new and perfectly matched at 82 and 82 where 58 is the minimum GOOD level on my TV7 tester. That's well within the new range. The flash getters are full, sharp and shiny. The JJ 300B is considered one of the best reasonably priced 300Bs. I will ship anywhere in the USA via US Postal Service Priority Mail fully insured for $10.
