Extras ▼

 

The CV5072 is the UK service designation for the commercial EZ81 and the envelope carries both Type designations.
In use the maximum reservoir capacitor would be limited to 50 µF and to prevent damage by excess current an effective series resistance of 230 Ohms is used.
The EZ81/CV5072. The two anode plates are stitched together and at the gap between them can be seen the white of the oxide coated cathode.
The anodes are identical with one mounted up and the other down. Each anode has two full length sections and two half length flanges to achieve the maximum area to radiate heat away..
A view of two of the half length plates coupled to the full length sections.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 70 mm tall.
