4 pcs. ultra rare Tung Sol/Cetron 6384 Red Bank NIB NOS tubes. I have tubes of both brands in pairs.
These tubes costed more than a car in their days and they are made of the best materials. They were used in air planes and cruise missiles. They can withstand 500G. Electrically they are a kind of 6L6 on steroids. Pinout is different though to avoid mixing of those tubes which the application would not permit. They have ceramic sockets.
$125 ea. ex. shipping. Paypal accepted.
