This RCA 83 is a full-wave mercury vapor rectifier tube.

The 83 rectifier tube is found in many vintage tube testers. In the most common Hickok tube tester circuits, an imbalance in the voltage drop across the diode sections in this results in an error in the Gm reading. For this reason, we offer 83 rectifier tubes that have identical voltage drops across each section. If getting the most accurate readings you can from your vintage tester is important to you, we recommend one of these “Hickok grade” 83 tubes.

This tube is sold individually. Photo is a sample from the lot.
