Radiomuseum says, "The Series 10-12 Electronamic Tube-Master is simple push button, master-lever type operated Vacuum tube and battery tester, incorporating the Electronamic Master tube testing circuit, designed by Precision engineers to indicate the overall performance merit of a vacuum tube in only one direct meter reading. ", and, judging by the schematic, http://www.antiqueradio.org/art/Precisio...ematic.jpg , I would say it will do all I need it to. If you notice, it has the headphone connection for noise test, as well as all the short and transconductance tests.
