Great price.
For sale is a
SINGLE (1)
piece of
Western Electric 310B Vacuum Tube, produced in 1966
I have three of these available for sale
separately
, all have the same date code of 6626 and same strength.
The tube was tested on Hickok TV-7B/U with reading of 50. Reading of 30 is the minimum good. So, this tube is good and very strong (probably close to NOS).
Physical condition is exactly as shown in pictures. There are kind of glue residues that I left to the new owner to clean. No loose pieces or rattling things inside the glass. The base is tight, and all pins are good.
I pack well and ship worldwide.
Again, choose the number of tubes you want to buy.
