AZ1, GZ32, U76, EZ35.
|Shown above is a Mullard AZ1 rectifier.
This has a P Type base and is of 106mm height. This has a 4v heater
with maximum voltage of 500v but max I of only 60mA.
||Shown above is a Mullard GZ32 rectifier. This
has an International Octal (I.O.) base and is of 115mm height. It can pass
quite a high current of 250mA, at a voltages of up to 350v. Still
used in some quality valve amplifiers today. 5v heater.
|Two less common valves in the panel above.
The U76 by Marconi Osram has an I.O. base and heater of 30v. Maximum
voltage of 350v and max I of 100mA.
||Shown above is a EZ35 from Mullard. This has an
I.O. base and 6.3v heater. Max I of 70mA with maximum voltage of
325v. The 6.3v heater will be the same as the heater voltage of the
other valves, so this device has to incorporate a high cathode - heater
insulation characteristic to reduce the risk of flashover of the H.T. to
