Another suggestion is to purchase a full box of cores.I few years ago I 
purchased 65 pcs of the 2.4" cores from Arrow.  About 12 arrived cracked in 
shipping. Of course Arrow made good on the damaged cores.In a later purchase I 
ordered a full box of 100 pcs, again from Arrow, and they arrived in great 
condition. 73,Gary K9GS

List of ferrite sources and prices Thanks, Gary.Don't forget to include 
shipping costs when comparing quotations. I often make small purchases at 
Arrow, because they offer free overnight shipping for a $50 order for anything 
they have in stock, and they stock a lot of the Fair-Rite parts we are likely 
to need.73, Jim K9YCOn 9/28/2020 9:15 PM, Gary Johnson wrote:> Here’s a price

post this occasionally. Some of the entries were updated a couple months ago,

general comparison of prices and plenty of alternate sources to check. And 
you’ll quickly see why Palomar Engineers is the last place you want to go when 
buying ferrite.> > Gary NA6O> ————————————-> > Showing only suppliers with
