The 202VP is a variable-μ amplifier pentode designed for RF or IF amplification in superhet receivers where the stage gain is controlled by an AGC voltage derived from the rectified signal. Our other 201VP has a differnt style of letting that is better condition.
The 202VP and 202VPB are electrically identical, the difference being that for the 202VPB the top cap connection is the control grid and pin 5 is the anode.
The heater is designed to draw 200 mA at approximately 20.0 Volts and be connected as part of a heater chain across the mains supply either AC or DC.
The reverse is plain zinc paint.
The classic envelope is 44 mm in diameter, and excluding the B7 base pins is 105 mm tall.
References: 1040 & 1043. Type 202VP was first introduced in 1938.
