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.

Make sure you use the same amperage and type, fast or slow blow fuse or yeah your warranty might not be honored.

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.
