[TowerTalk] Ferrite type 31 price list

[Gary Johnson]

I did some online shopping, so for your convenience here are current prices from many suppliers for the type 31 toroids and big clamp-ons that are so useful as chokes. “In stock” means >100 available at the moment.  There are some good deals out there, even in relatively small quantities.
