Re: Ferrite Beads - Bad idea?

I've run ferrite beads on the leads to the HV transformer and secondary HV
leads out of the HV transformer for years. They work well and I have had
no heating problems. Like Robert, I have not put them on the primary
You may want to try them this way and see if there is a decrease in tank
RMS voltage and rise times.
