1 - 5842(417A) Amperex Tube Made in USA Black Plates Gold Pins Codes 62-21 = 1963 NOS NIB Tested on enhanced Tripplett E3444 Laboratory Tester prepared by Paul Hart of Roswell Ga. 24,500 micromhos @ 26 mA Bogey(100%) = 25,000 @ 25 mA +/- 10% The measurements in this listing were taken on a Triplett 3444 modified to test the tube as an amplifier in accordance with RMA/EIA specifications, utilized by all US and most foreign tube manufacturers. This tester applies test conditions for this tube as shown below (including the precise filament voltage) and then measures transconductance (gm) in accordance with the engineering definition of gm. Tubes may also be operated under the test conditions for extended periods to be sure that it is stable. A tube must be tested in this manner to compare its test results with the manufacturer’s original intent or with other tubes of the same type. Most tube testers do not apply the test conditions required or conduct a valid gm test. For more details on the test and our test equipment, please contact us.The test conditions for this listing are__150_Volts plate, __150_Volts screen, ___60___Volts bias or Cathode resistance(CBR) What were you tubes tested at? I do combine S&H

Item is one unmatched lot of Amperex 5842 JAN 5842 vacuum tubes. These tubes are clean and seem to have had minimal use. However, they are not in their original boxes so I am selling them as used. These tubes and have been tested and are good. These tubes were manufactured in USA. All tested tubes are at least GOOD on my Superior Instrument tube tester (most 7, 8 or 9 pin tubes) or meet the minimum strength on my U-Test-Em drug store tester (most other tubes). If a tube is labelled as untested, it is because I do not have the necesssary equipment to test it. All tubes that dont meet your expectations can be returned regardless of their test status. Sets of vacuum tubes labelled as pairs, quartets, sets, etc, came to me grouped together or labelled as such. My tube testers are not sophisticated enough to guarantee that all sets of tubes are fully matched correctly. Again, if you are unsatisfied with the tubes you receive, you can send them back for a refund. --> All items are inspected to ensure that they ship in working order ready to use. Any damage or wear outside of that which comes from normal usage is noted above in the description. Photos are of the actual item for sale, or if more than one is available, representative of any of them. Save on Shipping!!! Single items ship to anywhere in the USA at the shipping price listed.
