You are bidding on a pair of vintage RCA type 866A radio/audio rectifier tubes.  These are new tubes that came from a bulk pack, so there are no boxes.  I tested them after taking the photos to avoid any mercury vapor fog from obscuring the internal elements.  Both tested well above the minimum with a quick test on my TV-7 tester.  They are identical with the same date code, 69-43, and have the larger ST shaped envelopes.  They should make a great pair for your power supply.  Shipping weight is 1.5 pounds.  Several additional pairs are available.  Please see my other auctions for more interesting radio and audio items, and tubes.
