-- That's the tube..but it's not the one I have enquired about. I have mine in hand and was hoping for some specs so suitability could be determined for use in an amp. Cecil K5DL ___________________

-- The anode measures just over 2.5" in diameter and 1.5" tall. Overall length of the tube is 4.5". Weighs in at 6.95 lbs so it's fairly heavy. Cecil K5DL ___________________________________________

They are the same tube. Used by the bushel in large phased array radars. Carl _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman
