This listing is for a good used vintage RCA type 5U4GB full-wave rectifier vacuum tube.

This tube tested great on a reliable Hickock 800A tube tester. 

The sections tested at 2600/2600 on a scale of 0-3000, where 1500 or more is "GOOD".   ...and NO shorts or gas detected.

Ref:  New tubes will typically test at 2600+/2600+ on this tester.

This tube tested as good as some NOS tubes would test and has perfectly matched sections!
