The CV10761 (DY87) is a television EHT rectifier introduced in 1956. It was designed to have its heater supply produced by an overwind on the line output transformer. The 18,000 Volt rating places this as a rectifier for medium sized monochrome televisions.
Electrically the DY87 is identical to the DY86. The DY87 has the glass treated with silicone to improve insulation in humid environments.
This imported rectifier has both the CV reference and the commercial DY87 on the glass.
The open end of the anode bell is shielded by the lower screening ring. This limits the escape of X-rays.
The thin glass tube envelope is 21 mm in diameter, and excluding the B9A base pins is 62 mm tall.
