Every so often I update this compendium of ferrite prices. While prices are of
course up from a few years ago, most suppliers have a good stock.
Congratulations to the low-price winner for our favorite 2.4-inch mix 31: Pro
Audio Engineering. So keep this list handy as a starting point for your
shopping.

Price survey on ferrite toroids and clamp-ons for ham RFI applications
Gary NA6O. Updated Oct 2022.
Showing only suppliers with websites that list inventory and allow online
ordering. When ordering 2.4-inch toroids, order in multiples of 10, then most
suppliers will pack them in original factory-molded foam sheets.
------------
Call these companies for quotes. Prices in larger quantities often beat
anything listed here.
