Vintage U.S. ARMY RCA Radiotron 830B Vacuum Tubes (lot of 2 two)

Description

Lot of 2 (two)
Vintage U.S. ARMY RCA  RADIOTRON 830B Vacuum Tubes. The boxes are in rough shape but the original wrapping on the tubes look like they've never been removed, (until I removed it to inspect and take pics). The tube may have been handled without gloves so a quick cleaning with rubbing alcohol prior to use is advised. I have a number of these types of vacuum tubes and other items,(please see other listed items). They were all purchased at an estate sale and the owner ran a HAM radio. I am unfamiliar with these items and don't have the equipment to test properly so please check the pictures closely. I inspected for cracked or broken tubes and looked inside to try and see any damage or burning of the wiring and that's about the extent of my testing. These items are also used for the construction of steampunk creations and audiophiles use them in the building or restoration of older analog devices.
What you see is what you get so please look at pictures, and ask any ?’s before bidding.
