Scott, The resistor should be 12 Ohms nominal, I'd try installing a 12 Ohm and see what happens. The lamp should light within 10 seconds or so of applying power. If you have a spectrum analyzer you can place a loose wire close to the lamp assy and see the approx 120Mhz signal if it's oscillating! The lamp will be a whitish color when cold and a more reddish violet if hot. Cheers, Corby
