The 2A3 bias voltage is 45 volts at the most standard operating point - see the link for a typical data sheet.
What is called the filament voltage is applied across the filament, measured with one meter probe on pin 1 and the other on pin 4. Really, there is no such thing as a voltage; there are only voltage differences. Usually but nowhere near always, one of the probes is on the ground - but even then, sometimes you also need to choose between signal ground, power supply ground, and safety ground.
