Cold cathode tubes use an inverter to generate the voltages needed.  I would
not want to have that sort of electrical noise near my system.  They do look
way cool but noise is not a good trade-off...  Same deal with using a
switching supply for power.

I wondered if the inverter would create any appreciable noise if it is
powered from an isolated source like a decent size 12VDC wall wart.  I
certrainly would not use up capacity on my linear synth power supply for
that.  The design I was contemplating would contain all the inverter widing
inside copper pipe.  I have a couple I bought to play with.  I'll have to do
some experimenting to see if I can detect any induced noise.

Do you have any particular experience with them causing noise in audio gear?
Thanks for the tip on the low voltage wiring.  I will check that out as I
consider options.

Thanks
