Mullard ECC801's / 12AT7 / 6201 / (4) Gold Pins N.O.S. Tube (1) 4700/4825 " " (2) 4725/4700 " " (3) 4725/4775 " " (4) 4600/4725 I bought these as 2 matched sets back about 2 years from seller triodeel ( 2215 . they w in my amp after testing for approx. 1 -2 hrs at the most. Flashing is brite / Actually they are more stable now as to the was they will read as to NEW TUBES that will change some after being burnt in some. My Hickok 800 scale only goes to 6000 micromho max. All tubes are check for Shorts/Leaks , Gas , Life, Micromho A tube should not be tested if it fails the first test which is Shorts or Leaks test depends what the tester manufacture wants to call the test. All the tubes for auction are those I've collected in the last couple years for my equipment. I was looking to find the best sounding tube for my Brand Amplifers. Most not all of these tubes have been Audio system checked in my Vacuum Tube Logic ( VTL ST-85 ) or (MB125) also In the process I have weeded out a lot of tubes that w susposed to be N.O.S and strong testing all being said testers will check differently even 2 of the same brand / type. But be assured they will test as close together as stated. Any complaints, Please let me know and I'll do my best to make you happy. USA buyer only!! Buyers with score of 10 or less please email first. read more
