I have a Dyna-Jet 707 tube tester and I was wondering how it compares to the famous TV/7DU military tube tester.

Thats like comparing a Ford to a Rolls Royce

::So if I get the same readings on a tube using a TV/7DU
as I get with a 707, what is the advantage besides bragging rights? I just want to know whether to pay the outlandish price for one or stick with the Calibrated Dyna Jet 707 and go from there. I use this tester for the newer type and a Precession 612 for the older tubes.

The 707 uses the same basic Gm test circuit as the Hickok. It also has a very good grid leakage test. They were used by many service men over the years and are very good testers. Buy a Hickok if you want one but there is no particular advantage unless you need to test the old 4,5,6, and 7 pin tubes. Even then you can make adapters for a lot less money.

Be aware that if you do buy a Hickok you may need to refurbish it regardless of any assurances that "it works" or "it has been gone through and calibrated". Hickoks have become status symbols among some, leading to silly prices.

Thanks for the reply. I do have a Hickok cardomatic in my collection and it is in good shape but the case looks like 20 miles of bad road. It does have a full card case. I think for what I do I will stay with the Dyna-Jet 707 and the precision 612 tester. Thanks for the info.
