Brian - You can check for continuity in the heater circuit. Because of the tap on a 35Z5 for a pilot light this means there should be a small resistance between pins 2 & 7, also between pins 2 & 3, and between pins 3 & 7. The most important measurement is between pins 2 & 7 - if that is open, the tube is shot.
The meter should indicate an open circuit from pin 8 to all other pins, and from pin 5 to all other pins.
If the heater circuit is continuous, there is a good chance that the tube will work, at least a little.
