hi so i bought a set of 12" cold dual cathodes last week, tried setting them up but they didnt work. I thought it was because one was faulty, had a slight crack in it, got the replacement sent out today, no cracks or anything in the tubes, still doesnt work.
This is how ive fitted it, dual inverter is connected to psu cable (the cable cannot be faulty because it also power 2x 80mm fans through the same one).
hooked up each cathode to the dual inverter and powered on the pc, no neons.
PSU is a 700W OCZ GameXStream so should power this fine.
hi spartacus, yes the on switch is on, i have tried two inverters from the same set of neons, they look rather flimsy, where as the cathodes look in perfect condition on the tube and filament things inside.
i wonder if its worth getting a inverter seperate? and if so can you get branded ones?
Cold cathode is the type of tube, each one should have two connections, one is the anode and the other is the cathode, if the inverter supplies AC it should not mater which connection is which, but you could try reversing the connections to get them to strike, also the striking voltage will be higher than the working voltage. Make sure you have an inverter can supply enough volts to strike the tube.
thanks spartacus - got it in the end ;) ive had it at 3.8ghz but keep at 3.72ghz, better then the p5-e sli if you remember :)
wiz-king, i have one cathode here, it has two wires coming out the end, but only one plastic connector, which only fits into the inverter one way. The inverter uses a 2 pin (fan like connector), which has a standard male/female molex on the end. i will try again later, each cathode in turn.
Just one further thought. I've rewired mine to remove the switch and the molex pass through connector. I did notice that the pins in the molex were loose and not fully inserted. You may want to check that area.
I did find that if you have them on for about 12 hours a day then they last around 3 months before going very dim.
