The 0A3 is a cold cathode voltage regulating tube. It operates a bit like a neon bulb, and will glow when in operation. You can check if it is working by measuring the voltage between pins 2 and 5 while it is in operation. The voltage shouyld be about 75 volts.
Here is a link to the data sheet: https://frank.pocnet.net/sheets/049/0/0A3.pdf

It is same as Zener for solid state.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
