Important
This I-177 data-base was created using data from I-177 beta 1.08 worksheet, from July 5, 2002. A great compilation by Nolam E. Lee.
Note A: The plate cap of the tube under test should be connected to the upper left contact of the 6-pin (C) socket. A 12-inch lead with clip and bananna plug is provided for this purpose.
Note B: Connect the plate cap (nearest the operator) to the upper left contact of the 6-pin (C) socket; use the lead provided. Connect the grid lead to the remaining cap on the tube.
Note C: Set the MICROMHOS switch at 6000 when testing this section if the tube tester bears either Order No. 27613-Phila-44-52 or 52346-Phila-45-10 on the nomenclature plate.
Note D: This test is only a partial indication of a good tube. A complete test is only possible when using equipment.
Note E: Do not tap on this tube when testing for short because damage to the tube may result.
Note F: The Mutual Conductance values listed are averages for new tubes and only for a guide.
