I just acquired a nice pair of used 572B's which I would like to test and match before storing them as spares for my SB-200. I've checked (googled) all online sources and my 666-07 data chart and supplements for both the 811 and 572B tubes and can not find anything. Has anyone developed a set of settings for the Eico 666 tester which would enable me to determine the relative emission and/or shorts/leakage for either oif these tubes? Much appreciated. Thanks Jack
