This is for an RCA 6EM5 with black plates and a top round getter vintage radio preamp tube. It is in good clean condition and has decent labeling and tested good strong on my tester as seen in the pictures at 104. Guaranteed good to play. 

Tubes are checked for shorts and value, minimum good is 70 and max is 130. This tube passed all tests. This is a vintage used made in USA tube. See the pictures for condition, testing and all that is included.
