    I just obtained a Hickok 600A and trying to test the following Cunningham tubes from a Crosley Playtime Model 124 but I cannot find the equivalent tube types to set the the 600A accordingly:

    RCA Cunningham 80
    RCA Cunningham 47
    RCA Cunningham 35
    RCA Cunningham 27

    Would appreciate if you can assist me with tube types. Thanks much.

      Sorry, I don’t have specific information about these tubes as tested by the Hickok. I will check my documentation next weel when I’m back at home …
