Collection: EZ81, 6CA4, CV5072, U709 UU12, RECTIFIER B9A
The EZ81 was introduced by Mullard as a high current B9A rectifier, the low power rectifier offered by Mullard was the 90 mA EZ80. Prior to marketing the EZ81, Mullard designs used the GZ34. In use the maximum reservoir capacitor would be limited to 50 µF and to prevent damage by excess current a series resistance of 230 Ohms is used. The thin glass tube envelope is 19 mm in diameter and excluding the B9A base pins is 70 mm tall. The EZ81 saw much use in classic hifi and classic guitar amplifier designs and finds use today in some new design valve pre amplifiers.
