Hi.

I've been using a pair of AR 18s speakers as nearfield monitors for many
years, and I'd like to keep using them. The trouble is about every 9
months or so, I have to replace a tweeter. I'm using a Hafler Pro2400
amp (120 watts per side @ 8 ohms) and the speakers are rated "50 watts
nominal/ 60 watts Maximum". I never monitor at too high a level, but
there are those moments where loud source material will find it's way to
them (Mr. Hi-hat when I'm not expecting it etc.).

The AR manual suggests that when the speakers are going to be subjected
to this kind of enviromnent, that you use a fuse. Their suggested fuse
is a Bussman FNM 1 1/4, in a fuse block, on the back of the cabinet
inline with either the + or - input. FNM 1 1/4 fuses are really hard to
find! Can anyone suggest a substitute? Is this a bad idea in general?
Guide me.........

Many Thanks!
