Tube électronique UY85

The UY85 is a half wave rectifier and would be used on small universal (AC/DC) mains appliances. The heater chain would draw 100 mA and this was to enable the small number of valves used in a broadcast radio receiver to be run without a large dropper (ballast) resister.
The UY85 can work into a maximum reservoir capacitance of 100 µF, as protection a series resistance of 100 Ohms minimum is required.
The thin glass tube envelope is 20 mm in diameter, and excluding the B9A base pins is 57 mm tall.
