How many fuses in a McIntosh MC275?


Hello.

I have upgraded the main fuse in my MC275 mk IV, the one that can be replaced from the outside, a 200 mA slo blow. But I keep reading about several fuses in amps, some for the speaker outputs...I don't know if mine has. Does anyone know?

Thanks!

WOW No way! Fuses are usually visible and sometimes resistors are set to work as a fuse. Upgrading or replacing fuses is the most ridiculous upgrade you'll ever get.
I see...fuses are a ridiculous upgrade to you. Yet I heard improvements every time I upgraded from a std fuse to an audiophile fuse.

Why do you waist time trying to convince me of something I did not even ask about? You are surely waisting my time trying to honestly understand if you had something to say...oh well...

Thanks
Are you sure it is a 200mA? From what I see in the service menu, the main power fuse is 250V 4A slow-blow and two more inside for speakers output are 250V 2A slow-blow. You can download a service menu from here.
you can only prove hearing improvements on the blind a/b tests. blind tests is where all audi'o'philes fail to ID stock fuse from aftermarket and other silly unnecessary stuff.
as you know, fuses tend to blow and usually are all visible on the pcb or direct wiring. the improvement you've heard is possibly from the quality of the contact so all you need to do is to clean fuse terminals with qtip and contact cleaner.
I read the schematic and found that the two fuses inside are actually for filament heaters, not speaker outputs.
