Being the new owner of a Zenith 8G005 Trans-oceanic, and doing the preparations before restoration, I got out the trusty EICO 666 tube tester to test the tubes. Imagine my surprise to find that none of the tubes were listed in any of the charts I have. What to do? In a fit of inspiration, I checked the listings for the EICO 667, and sure enough the tubes were listed there (except for the 117Z6, another story). Could I be so lucky the settings would work for the 666 as well? Sure enough they do - the grid and plate settings are the same, as well as the V and S levers and shorts/merit buttons. For the other levers, just follow the numbers from left to right as you would otherwise, using only the first 10, ignoring the space between them and also the last 4 numbers. Of course, this only works for tubes with less than 10 pins, but even still, it's a tremendous help. 73 and good DX,
