I checked the wires to the grid caps for continuity , they test fine. I have an Eico 666 tube tester . It doesn't list the 1A6 on the built in chart. There's a socket it fits into, and a grid cap wire.
Is it possible to test the tube on this tester. I can guess the filament voltage should be set at 2 volts. I'm stumped on the rest.
