2 Type 6CA4 / EZ81 Vacuum Tubes

These used tubes have been tested for emissions. On my Hickok TV-7 tester they read 53/53 and 53/53. A reading of 40 would represent the minimum recommended value. They feature gray plates and halo getters.

The 6CA4 (aka EZ81) full wave rectifier was used in many different moderate output audio amplifiers, especially in circuits that used 6BQ5 / EL84 or 7189 power output tubes.
