Hi again Matt,

I'm no expert either but unless I'm mistaken we have it right. The hot end is the forward end of the fuse which as you say goes straight in to the power supply. The SR is on the other end which is the fuse holder itself with the fuse values showing left to right as we read. Also, I think the power supply rush when turning on the unit first before the power supply eliminates the current rush because the rectifier tubes warm up slower. Again, someone else is the forum like HeavyMech knows way more on this stuff.

Happy listening

Greg

Thanks!

I have popped a few Synergistic fuses but now realize I have to go up a number, from Large 2A to 2.5. I think the Purple Fuse is the greatest value in audio performance, almost equivalent to upgrading IC's or PC's. Only fuse is accessible in my VTL 7.5 iii pre, and my Sansui TU-1X tuner. The pre did marvels. Will similar improvement work on the Sansui tuner, ca. 1977? Thx. Neal

I upgraded the fuses on my Magnepan 1.7i's from stock to Synergistic Purples and it was a revelation. The stock fuses sounded muffled and full of noise, I had a room of regular non audiophile people and every single one of them said the sound quality at least doubled in quality on the purple fuses. But! the 4 AMP Maggie recommended amperage value on the purples BLEW! So I bypassed ampage and got the 15AMP purples for sheer musicality happily in sonic nirvana to void my maggie warranty :)

Intentionally ordered a 6.3A purple fuse for my 5A Rogue Atlas Magnum II. Sounds great and the Rogue hasn’t blown up...I will certainly let this forum know if there’s a problem.
