Hi Pierre, did you see any light at all from the tube? You may be OK.....see Paolo's astute observation from his email.
Do you have a multimeter? Have you checked that you have 170V DC (or thereabouts) coming from the little power supply? Note, that the IN-1 tubes have a notoriously short life-span.....

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