The EM85E tuning indicator uses the closing of two bars to indicate tuning or voltage level. The grid voltage change for full deflection is from -14 to 0 volts. Pin 7 is defined as a deflection electrode and the anode of the indicator is called the target. The grid of the indicator is strapped to the cathode. The first half of the valve is a triode amplifier as is usual.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 62 mm tall.
