Sensibly equivalent¶ to:
The GZ33 shares base pin layout with the GZ32 and the GZ34. All are full wave rectifiers with a rating of 500 Volts for the anodes. The GZ34 is an upgrade to the GZ32 and both are rated at 125 mA rectifier current. The GZ33, however, is a high current version and is rated at 250 mA rectified current, and unlike its lower rated counterparts is not given a maximum reservoir current rating, but 200 µF would seem a maximum value that would be used in practice. The cathode is tied to one side of the heater as heater-cathode insulation would not be sufficient to withstand the full voltage.
The classic envelope is 42 mm in diameter and, excluding the IO base pins, is 123 mm tall.
