Brand new, never used! Two Synergistic Research Blue Quantum Fuses. We took them out of the box for taking pictures only. They both are the 5mmx20mm Slo-blow version, 3.15A 250V. The new SR BLUE Quantum Fuse was developed over a two year period and represents the most advanced UEF Technology to date. At its heart is a completely new UEF / Graphene coating that delivers a dramatic increase in resolution and holographic realism over SR Black. And thanks to a new conditioning process, break-in time is cut in half. In fact, a brand new out-of-the-box BLUE Fuse should significantly outperform a fully broken-in BLACK Fuse and it only gets better from there with full performance after 200 hours of continues power. To find out how good your components really are audition the new SR BLUE Quantum Fuse today. Retail price is 150 euro for one Blue Fuse, now for 99 euro for one only.
