6087
6087 has no equivalent designation confirmed by the archive. Completed sales put the typical price at $21.24 per tube.
The 6087 is a full-wave high-vacuum rectifier for use in power supplies of moderate current requirements. It incorporates a coated unipotential cathode which is internally connected to the filament. The heater voltage is 5.0 volts (AC or DC) at 2.0 amperes. The tube is designed for dependable life and reliable service under the exacting conditions encountered in mobile and aircraft applications, with a high degree of mechanical strength and a heater-cathode construction designed to withstand many-thousand cycles of intermittent operation. It can perform satisfactorily at altitudes as high as 60,000 feet. Within the limitations of its maximum ratings, the 6087 is a replacement for the 5Y3-GT. The heating time is approximately the same as that of other heater-cathode tubes in the equipment.
Construction
The 6087 has a T-9 glass envelope and a short intermediate-shell octal 5-pin base, B5-62. The mounting position is any. Pin 1 has no connection; pin 2 is the heater; pin 4 is plate no. 2; pin 6 is plate no. 1; pin 8 is heater and cathode.
Ratings
The 6087 is rated for rectifier service with sinusoidal supply voltages in the frequency range of 25 to 1000 cycles per second. The maximum peak inverse plate voltage is 1400 volts. The maximum steady-state peak plate current is 375 milliamperes per plate, and the maximum transient peak plate current is 1.7 amperes per plate with a maximum duration of 0.2 second. The maximum bulb temperature at the hottest point is 220 degrees C (absolute maximum), and the maximum peak impact acceleration is 700 G.
