The VU120A is an EHT rectifier with a cylindrical anode. The cathode runs vertically 6 mm from the anode wall, the top end of the cathode is connected to a plate and a stout wire passes back down inside the anode cavity. The heater is coated for insulation and four lengths are folded into the cathode tube and connected at the pinch end. The maximum reservoir capacitor is 0.25 µF, and the minimum series resistance is 10 kOhms.
See also SU120A.
The classic envelope is 46 mm in diameter and, excluding the B4 pins is 109 mm tall.
