Any CARY CAD 300SEI owners who use Furutech fuses?

I realize that this is an old thread but maybe someone is still paying attention? Supposedly the HiFi Tuning fuses are directional, according to the arrow on the logo. But it is not clear, on the 300SEI, which way the current runs. The main fuse is located directly beneath the plug. So, does anyone know the correct orientation? I assume that with the tube fuse, the arrow should point toward the amp, no?

Thanks Rodman. So you mean that the tube fuse arrow is pointed toward the amp, yes? But do you have any ideas about the proper orientation of the main fuse (the one directly beneath the plug on the 300SEI)? I think that normally you would point the arrow away from the AC port, but you can't use that rule here because the fuse is directly beneath. I suppose I could open it up and look at it.
