Just a minor quibble and off topic, but a NE-2 does not pull enough current to function as a supply regulator. A for-purpose tube (like the 0B2) has to shunt a large enough percentage of the supply current in order to regulate.
0Z4 is a cold cathode rectifier for car radios (though possibly it could be re-purposed as a regulator in some one-off project.
