Up
| This Westinghouse 803 tube came from an estate sale. I could not power up this tube and check electrically since I have no equipment that uses an 803. I did check the filament for continuity, however, and it is good. Also, there are no shorts between elements and no loose particles inside. The getter looks good and the base is firmly attached to the glass envelope. I have no reason to believe this is not a perfectly good tube. |
