Just picked one of these up and will rebuild soon. I have many 8417's and 7868's that i need to test. The chart doesn't list these. Are there other #'s for these tubes? Has anyone used this tester for these tubes?

Thanks in advance.........curley

There really isn't anything like a 8417, pretty high transcon 7AC pinout tubes.

A 6550 or KT88 setting will let you "test" to see if it works, maybe make a pile.
(then compare all your 8417 to "make" a setting)

The 7868 is basically the same as an 7591 with different basing, that may help.

Testing 7868 tube

The 707 socket #'s don't translate to the B&K Dyna Quik 500. Has anyone tested 7868's on one of these? Thanks to all of you for your help.
