GE 5814A triple mica: From Andrew's Tube Review: WOW! This is an inredible tube, that I let sit in my box of tubes for the longest time without really giving it a shot. In a word, this tube is TIGHT. Controlled, yet full bass.. Nice sparkle, but not too bright.. really a linear sound tube with a hint of American tube warmth of course. Tested on a Hi End Maxi-Preamp II tester for Gain (Mu), Transconductance (Gm), and Noise (dB)., the tubes shown in the photos are the exact same tubes that you will receive. All tests are continuously sampled, averaged and then updated every 250 milliseconds for the most accurate measurement. Warranties: Sold as is with no warranty, please view all the photographs provided on the listing.
