    Heathkit tube checker specs

    Post by baddog1946 on Sat Aug 04, 2018 9:19 am

    I have a Heathkit TC-3 tube checker and I need the test settings for the newer tube types used in VTA products. Can anyone provide the settings for the following tubes? KT-120, KT-88.

    Any hints where I could find them is also appreciated.
    cheers

    No TC 3

    I do not have a TC 3. It is an emission tester but should give good basic results. For my Hickok tester I used the 6550 settings for the KT88 and they work out just fine. If your TC 3 has the 6550 settings it would probably be a good starting point until something more definitive is specified.

    The KT 120 is in the same family as the KT 88/6550 so I think your settings would be the same. The KT 120 may actually have to have higher emissions to be good compared to a KT 88. More of a guess than a qualified answer.

    More responses from this group would be good.

    KT88 = 6550
    5881 = 6L6 =~ EL34/6CA7/KT77

    And the Euro-chart is below the main chart.

    Oops - I nearly missed linking the original chart that has such basics as the 5AR5. 6CA7 and such.

    Enjoy, as emissions-testers go, the TC3 is amongst the best.
