tom8999 OPDon’t get sucked in, just use the one that came new with the Krell KAV 400 xi, Krell aren’t stupid they know what works best as they are EE design technicians and not voodooist. Save your money for something real like an equipment upgrade instead.
I just wanted to buy the correct fuse that I can access without opening up my equipment.
I am still on the fence and have not ordered anything as yet.
There’s reason why many of these snake oil fuse threads get shut down.
