Loctal Rectifiers

Does anyone have a recommendation for a 5V Loctal rectifier? Preferably something more or less equivalent to the GZ34.

5AZ4 is the only one I know of... it's equivalent to 5Y4. There are 6V indirectly heated ones... 7Y4, 7Z4

AZ21... for 4 volts. Only need one resistor to decrease heater voltage from 5V to 4V. But it's very rare and hard to find tube...
