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.

You may be good at fixing cars, but you should stop giving bad advice about electronic equipment.

You are funny, again!! Cars?

 And who would certify me? LOL YOU? I'm rollin' on the floor..

International Machinist and Aerospace workers. NASA  at one point in my life, and a few other small "uncar" companies. I'm a HD master mechanic, retired. Hydraulics, tunnel boring machines, large diameter shaft boring vertical or horizontal, trench cutters, anchor drills.

Though I did serve part of my master/tec training at a Studebaker/Rambler/AMC shop in the 70s

I've opened every box on the planet and been paid for it all. Let alone stereo gear. Your funny! Do you really think the stereo world of electronics is "The high end" of electronic repair.. Holy cow buddy, wake up.. 

EEs don't work on stereo gear, just the ones that aren't working as electricians so they can get paid a decent wage. Been my experience.

Same with Sound Engineers, I've worked with a lot of sound engineers,
at  excavations all over, maybe one in 30 or so had anything to do with speakers, there is no money in it...

Your good advise is someone is "wasting money" when they get a "NOTED" improvement by changing a fuse.
Again, good advise, need not have unkind words, sir! If you listen you might learn, something YOU can use..

"The fuse won't work man"
Funny guy.

Regards maybe...
I read your post on another thread.  You are CLEARLY not one to be posting about fixing anything.  You are funny!  LOL.  Funny guy!
Santsuru, in regards to #2, you should contact the manufacturer before opening the unit and changing any parts, including fuses. All manufacturers have guiding documents stating their warranty policy, but it’s always best to call/e-mail and ask first. That way, they can make a note in their system (make sure to get the contacts name, department, and note the date), and if a serious warranty issue occurs later on, your fuse change will have been documented.
If you bought gear NEW from a reputable manufacturer/dealer network, your warranty will be fine. If you didn’t--oops!
Sure are a lot of void warranties in our group if you can't even open it up. All those interior amp pics on the web are of out-of-warranty amps.
Hilarious!
Funny stuff. Don’t open that lid to change a fuse or tube or you will void warranty? You must be kidding right? Oh my.
