Vacuum Tube - 6087 / 5Y3WGTB, Rectifier, Full Wave
New-Old-Stock (NOS) tube.
The 6087 is a full-wave high-vacuum rectifier for use in power supplies of moderate current requirements. The tube incorporates a unipotential cathode which is internally connected to the filament. The heating time of the tube, consequently, is approximately the same as that of other heater-cathode tubes in the equipment. This construction minimizes excessive surge voltages across the filter input capacitors during the warm-up period.
The 6087 is especially designed to assure dependable life and reliable service under the exacting conditions encountered in mobile and aircraft applications. Features include a high degree of mechanical strength, a heater-cathode construction designed to withstand many thousand cycles of intermittent operation, and the ability to perform satisfactorily at altitudes as high as 60,000 feet. Within the limitations of its maximum ratings, the 6087 is a replacement for the 5Y3GT.
