Ferrites

Ferrite toroids and snap-on chokes for audio and HF purposes - we stock several types of toroid for HF Baluns/Chokes as well as the 31-mix "Problem Solver" which makes a great mains-filter and ad-hoc choke. We also have 5mm+9mm snap-on "domestic" ferrites for taming audio/Hi-Fi/USB issues when near strong RF.
