Notes

Directly heated (filament cathode) — observe heater warm-up time before applying B+ to protect the tube and filter capacitors.
The 5Z3P is a modern Chinese octal-base version of the classic 5Z3 (which used a UX4 base). Electrically equivalent to the 5U4G.
The Chinese datasheet specifies a minimum external anode circuit resistance of 2 kΩ and a maximum filter capacitor of 4 µF for capacitor-input operation.
Available in several quality grades: J (military general), T (military special), Q (high reliability). The 5Z3P-J and 5Z3PAT are military-grade variants.
Voltage drop is not explicitly stated in the Chinese datasheet; the value listed is estimated from the output voltage curves and is consistent with 5U4G data (~44–47 V at rated current).
