Hi LF-ers...
I have a problem with 3C85 toroids...it's unpossible to buy it in
Slovakia. But a lot of Amidon and Pramet (Czech company) toroids are
available. I think an equivalent of 3C85 is Amidon FT-xx-77 (xx is a
diameter, for examp. FT-140-77 is diameter 36,5mm). Here are a lot of Pramet
H20 toroids available for a very good price. I have also parameters of this
material, so if you have interest, I can send it to you to compare it with
3C85.
