I have no fuses in my MMGs or 3.7s. :-)

My MMGs have been without fuses practically since I got them over 10 years ago. I've been walking the rope without a safety net with my 3.7s for about a year. The protection provided by the fuses is questionable when it comes to the ribbons and they aren't tough to replace if I ever melt one. I'm not too worried about that anyway. Sonically speaking (and this is one of the very few places where a fuse may impact sonics), there's no fuse better than no fuse at all (or the fuse holder, or...). ;-)

I am at the point now, I want to bypass... - Mark Man 11:55:32 08/15/14 (2)
The Fuse and fuse holder...after living with the 3.7's for the past 11 months and pushing them as hard as I can in a condo...I see no need for them in the signal path...

When I had an HT set-up, I owned CC1 hooked up to EAD PowerMaster 2000, could not keep fuses in that at all...any volume over 90 dB's they were toast...I replaced the CC1 with a pair of MMG's for center channel, (20 times better than the CC1)...never had another issue...

FYI, if anybody can chime in, (Waz, Grant, Jben...), on how and what to use for the Bypass that would be greatly appreciated, I have a Engineer friend who is going to the soldering for me...I would prefer if this took place behind the faceplate...(Waz, I know you have post pictures of this, but I currently can't find them in a search)

Thanks
Mark

  I'm at work (Friday is one of my 3 days ;-), so I haven't access to any photos right now. Regardless, your engineer friend won't have the slightest bit of trouble with it as it's very obvious. The only gotcha is the left speaker (with tweeter-in positioning) - in mine, there was a wire that wouldn't reach the binding post after removing it from the fuse (or jumper/resistor connection).
  
  Send me a message and I'll email whatever you need to you.
  
  See the link below for an old photo. I'm done experimenting with resistors and chokes...and no longer using the wire nuts. The photo in the link below is the dreaded left speaker. One of these days, I'm removing the socks and checking out the crossovers. The only reason why I haven't done it yet is that those staples are tedious and I don't want to be without my speakers for a few days. I've entered the room with the intention of digging into them, but I end up listening to music instead. :-)

Nor do I. - grantv 12:09:08 08/01/14 (0)
Completely bypassed the fuse/holder altogether; wire-to-wire.
I also do not fuse my Magnepans! - Potzrebie 00:36:26 08/01/14 (0)
I have had the sound quality go south with fuses that test good.
I discovered this with MG IIa's back in the late 70's, and after replacing the fuses with a shorting bar, never looked back. Noticeable clearer mids and high frequencies without fuses.
The mid range and tweeters are robust, provided the amplifier is not driven into clipping, or you do not playback at insane volumes (peaks way above 95 dB).
I play loud sometimes, but have only blown the fuses twice (when I drove my amp into hard clipping, and when I used a bridged 800 w/c amp to show off) since the 70's.
But beware, accidents and amp failure can happen!
