Mullard describe the EZ41 full wave rectifier as being primarily for use in car radio receivers.
In the EZ41 full wave rectifier we see Mullard move from all glass with a base spigot and metal skirt, to a complete all glass design. The pins are still equi-spaced around the pin circle, but the skirt is a thickened region of the envelope and the locating device is a pip moulded into the glass.
The style of sealing the pressed glass foot to the envelope is typical of Philips machinery.
The cathode assembly runs the whole length of the electrode assembly and the two anodes are vertically stacked.
Each anode has two side flanges for fixings and another two plates at right angles making four radiating surfaces around the central cylindrical working space.
The maximum reservoir capacitor is 50 µF and the device must have a minimum series resistance of 325 Ohms.
The thin glass tube envelope is 20 mm in diameter and excluding the B8A base pins, is 52 mm tall.
