Alan--thanks. I think I will aim for a Jackson 648 series because I've seen that Eico tends to wander on their tube chart settings. Mind you, if the price is good, the Eico will work fine. I also saw a Supreme I-177-B listed for a GOOD price that claims to be a mil-spec dynamic conductance tester, which intrigues me. And the price is good enough that I can actually afford to order the documentation from another source for $11 or so.
