6e5s (6e5s) Heathkit IT-17 emissions tester settings
Tube tester setting derived from cross referencing pin diagrams and experimentation:
Tube Type Fil Plate Top (T) Bottom (B)
6E5C 2 6.3 30 CE GH Normal Short (Bold) not idetified
6E5C 4 6.3 0 F CEGH OPEN when Test Switch Activated
6E5C 4 6.3 0 CF ECH Closed when Test Switch Activated.
I do not know what Bottom (B) toggle switches normally show short when toggled. These are normally indicated by BOLD lettering.
These will possibly work with IT-21, IT-3117 and TC-3
