Could be remembering incorrectly, but I think the Marantz 2230 I just restored has 5 fuses in total.

Decisions, decisions...
Totally worth it!

Oh wait, it's just a fuse? I thought it was some magical device that dispensed espresso and hand jobs. 
This is all the romper room brigade needed: a ridiculously priced fuse to throw shade at the reasonably priced ones that can change the sound of one's system for the better.

Just how many here went to the link I provided and listened to what the engineers at Yamaha found?

All the best,
Nonoise
