hi. i am thinking to replace the vk200 choke with some turns of wire, on ferrite bead.

i have some pieces of this ferrite bead: FB-43-7351 from amidon (43 material)

look here:

how many turns i must use to have the same inductance with the vk200. i don't know how to calculate the number of turns, and also i don't know the vk200's inductance.

(the circuit is an mw band (600-1800khz) linear amplifier),

and the maximum current is 15A.

If i use 4 vk200 (in parallel ) i will use the same inductance or 1/4 inductance, It will work?
