You are bidding on a pair of new old stock Amperex type 7643 radio/audio tubes, made in Germany.  They have the PQ "Premium Quality" designation with gold pins, and are equivalent to E80CF tubes.  They come in their original boxes, but one box is poor.  I am unable to find any settings to test them, but will guarantee them to be strong, new usable tubes.  (I was advised to test these as 6BL8, and both test strong as such).They are identical tubes with strong markings with close date codes, BG6 D3D1, and BG5 D3C1.  They should sound great in your amplifier.  Shipping weight is 7 ounces.  Please see my other auctions for more interesting radio and audio items, and tubes.
