This BIN is for a lot of 51 unsearched Tubes. 50 are without box, 1 with a box. These will be totally picked randomly. I bought these from a  repair man over a decade ago, and have been in storage since. I have thousands. It was too much of a daunting task to sell these individually. They are unsearched and untested. Some are unmarked as well.This will be pulled at Random, so no requests. I will ship out in a Priority mail box, tight, with bubble wrap. They Will be a little dusty, been in storage for years. Various brands, a ton of obvious RCA, Zenith, Sylvania, GE and others.
