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!

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.

I read the schematic and found that the two fuses inside are actually for filament heaters, not speaker outputs.

Personally, I don't think it will improve sound if you upgrade those fuses.
