I have an Adcom GFA-555 with rack mounts.

No GFA-555 I find online for purchase, rack mounts or not, has the fuses visible at the front of the box like mine does.

I'm looking to get another one to run my ST4's in verticle bi-amp mode so I need identical specs. Is this an issue? (not sure why the fuses are the pop-out type when I don't see those anywhere else)

Thanks!
