Hi David,
Your comment about fuses and AC wall outlets compared to tube rolling rings much truth in certain circumstances. I've had the good fortune to audition 11 different brands of 300b tubes in my SET amplifier (these include generous loans from fellow audiogon members ). Each is unique, some subtle and others are quite obvious. The SR fuses (Black and Red ) elicited a greater sonic impact on my system than quite a few(but not all of them ) of the 300b tubes. These terrific fuses are far less expensive than those tubes. The very best 300bs have a bit more impact but definitely at a cost.
Charles,
