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.

Stock status fluctuates... Anyway, this will give you a 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.
