Stehno,
I have 4 fuses on my 125; one 6.3A per channel (rail fuses) and two 2A which are each in the signal path of both channels. I live in a very dry climate though, and have blown all 4 fuses on several occasions. I'm moving to Kansas in July, though, so maybe I'll fork out the $100 for 4 more. :)
Sirspeedy, I purchased my HiFi Tuning fuse from the guys at The Cable Company as well. http://www.fatwyre.com/
Good luck!
