HiFi Tuning Fuse Replacement Yamaha RN2000a

The R-N2000A needs anything but a tuning fuse. It's already balanced in its frequency response and the damping factor is high enough that it doesn't adversely affect the frequency response of your speakers so why the hell do you want to replace the fuse?

Boutique fuses are another way for the unscrupulous to extract money from you.

Since there doesn't seem to be a fuse tray on the outside, the only option is to take the top off the unit and look behind the iec plug and look for a fuse. I personally only switch fuses when they are accessible from the outside.
