Hi,
I was working on a real old school two-tube fluorescent desk lamp. There of course are two choke ballasts, one for each bulb, but one has a 4.7 uF AC capacitor in series with it. I can't find it on the Internet now but seems I remember that being done so that the flicker of one bulb will be out of phase with the flicker of the other, so that the user will perceive less flicker. Is that correct? Thanks.
