[Elecraft] pro audio engineering power supply for kx3 installing rf choke

[Richard watson]

Good morning listers,
I am a new (back after 20 years) ham and just received my power supply
from pro audio. I am visually impaired and wanted to know the best way
to open the rf choke that was included for the power supply cable.
thanks for any advice. Looking forward for my kx3 arriving next week!
thanks and 73
