Price reduced. Audio Magic M-1 internal fuse for UK PS Audio P20 Regenerator. This is the king of P20 internal fuses. Better than the SR Purple fuse which can sound a little thin at times. The M-1 adds more meat on the bone to the sound. Comes in the original Ring box for safe transportation. Smoke and pet free home. Clarification for potential buyers. The PS Audio P20 has an internal fuse, located near where the power cord inserts into the Regenerator. Its accessed by inserting a small screwdriver into the indent in the fuse holder. Upon turning this the fuse holder cap pops out and a UK P20 will have this small internal 5 amp slow blow fuse. The M-1 replaces this stock fuse and gives much better sound. Its supposed to be non directional but trying both ways will ascertain which orientation works best in your P20.
