Or simply check if there is 170volt coming from it with a volt meter. Also, if you have swapped anode/cathode, something should still light up without damage. There would be a glow.
Since you have it wired correctly (with a resistor) on the correct pins, even if the polarity is reversed, and you have 170volts output, then the tube is bad. There is no harm trying other tubes to see.
