I used this topic title so that we can add to it as other information and or brands come along.
This topic is for all brands of speakers, not one specific brand.
The only issue that jumps out at me is that the Advent/1 uses several different model fuses.
All slow blow, but not just the Bussmann FNM or Littlefuse FLM types.
I have never read any other mention of different models of fuses, in the same brand of speaker, of course, in any of my readings over the years.
There is possibly speaker systems that individually fuse their different drivers.
There has never, in my experience at least, suggestion of fast and/or slow fuses on the same speaker.
It would have been great if the manufacturers had exited connections for the purpose of individualy fusing drivers.
With the high cost of these particular fuses and their fuseholders, as well as their availablity or lack thereof, it is well worth while that we discus this subject.
There is a few conflicting fuse sizes recommended on the AR fusing sheets.
Originally when I posted those different sheets, I felt that they all should be posted, not just the latest, perhaps.
The earliest sheets did not have the future models, of course, and not all sheets listed every model as well.
I will be posting all of the fusing literature and photos that I have here shortly.
There will be some duplication with our library, but, I feel that this is a specialized topic and we need to keep all relative information as readily available as possible for future reference.
I do not have all fusing information or knowledge.
I welcome any added information or suggestions.
If I may suggest, let me add that new information or photo here for you in this original writeup.
It appears that I can edit my writeups for several years back.
That way this information is in one single folder rather than stretched a long way down onto separate pages, getting buried deeper into the pile of other topics.
Some photos were posted by members, or off the internet from different sources, without their permission.
I tried to show the different methods of attaching fuseholders to cabinets as well.
This certainly is not all encompassing to say the least.
Electro Sonic 2002 catalog listed the Bussmann FNM-2 amp slow blow fuse at $4.68 each here in Vancouver BC.
As you can see, pdf files can give you a visual description without them being downloaded, jpg files need to be looked at or downloaded to see their description.
I believe that the Dahlquist DQ-10 also has a fuseholder, which I do not have a photo of.
Missing still is also the AR-LST fuseholder photo.
Obviously .PDF is a better way to go and save when scanning.
I learn a little more each day.
Monday 20110425 UPDATE
I made that supplier an offer they can't refuse.
No, not like in the movie, The Godfather, LOL
Actually I emailed, Nancy, a suggestion, I will post the suggestion and response after I receive a reply.
Tuesday 20110426 UPDATE
In my email I suggested that, I was inquiring for everyone worldwide, not specifically for myself, a previous customer.
I tried to be honest and mentioned that the reality is maybe a purchase of 5 or 10 fuses would be a more realistic order.
A suggestion that the $15.00 minimum purchase amount and/or $10.00 minimum S&H charge maybe could be reduced.
Also mentioned was Kent's reference writeup about those NOS Rogan Bros 8-904 knobs which are generally limited to 8 for a pair of KLH Twelves.
I received a reply from, Nancy, this morning.
"I reduced the fuse price quite a bit. Priority mail to Canada #1 is generally $14.00 additional."
This is all I can do about this matter.
I see now that I did not show the link to that company or mention it's name.
