TWO USED TUBES.

RCA brand   

Tested on Hickok 600A. 

Unless otherwise noted, tubes are tested just before shipping, (to make sure I'm sending a good tube) not in advance.

There are many testers, which give a wide variety on readings. If our testers disagree, mine wins.

International buyers assume all responsibility for shipped merchandise. Shipping details are emailed to buyer when mailing lable is printed.
