Not only you need the 10k resistor, but you need to ground a cathode. In ASCII drawing:
+HV ----- 10k -----[Anode || Desired Cathode] ---- GND In your picture it looks reversed, whch is good since you didn't put the resistor.

Try 10K or so to test the tube. Do you know that you have 170V > on the output of the supply?
