Fuses and confusion

I am slowly upgrading my system and I am looking at the changing of fuses step. I have the following in my system:  Sunfire TGA-7401, Marantz AV8805, Carver Load Invariant amplifier, Marantz Ruby, and a Vault 2i. My questions are 1). Which of these components have\use fuses 2). Does changing the fuses invalidate the warranty? 3). Are there videos on changing the videos or do you just pop the hood and start looking. Please feel free to point out issues that I am not aware of and whether this is even relevant under my circumstances. Thanks in advance.

The Marantz AV8805 actually has a larger number of fuses and they are all located internally.  The main fuse is probably the biggest impact (usually on a small board right next to the IEC power cord socket).  I would go with a 2A fuse for this main fuse on the AV8805.

There are still a bunch of fuses all over the place within this unit.  It really depends how far you want to go in disassembling the unit and pulling out boards.  Probably not very far, lol.

1) You are absolutely wasting your time changing fuses.  The only possible fuse change that would affect the amp's sound is if there are fuses in line with the speakers.

2) If you open the chassis of a component and start messing with it's internal fuses you will unquestionably void your warranty, regardless of what anyone says here.  Don't be foolish.

...and 3) Millercarbon is a rather well-known shill for Synergistic Research and has hawked their questionable wares on many threads on this forum.  His advice is tantamount to shooting yourself in the foot as far as warranty goes.

Your funny too. Void the warranty? for replacing a fuse, funny guy, the only thing that WON'T void the warranty, is  replacing the fuse.

The void/tamper proof tape is actually void if there is a fuse under it.. That's a US requirement. ALL equipment can be looked at and serviced by YOU. YOU just might not be reimbursed, for you labor. I've always been reimbursed for my parts and a reasonable labor rate..

Just like your Chevy, Ford, BMW ect.. you can do the service and the work, it voids NO WARRANTY...

You sure sound like someone else that uses the "shill", word. What the heck is a shill? Sound's Yiddish.  Because I'm 10% American Jew, 15% American African, 25% American Native, and 40% American Irish, but 100 % blue eyed American demon! I'll let it slide, but no name callin...Oh! The Wifes, 100% American Latina... Cha Cha Cha, Amigo!
