Quick fuse question


Hello guys. I have a quick fuse question. I have a ARC D200 amp that uses a MDQ5A fuse.The MDQ is a dual element fuse. I have purchased some Aucharm fuses for my pre and phono stage and they sound great. What would be the replace size for the MDQ5A fuse? I put in a standard 5Afuse and the amp ate it for lunch. Thanks for your time and effort guys.

I know this, I have removed the fuse circuit a few times, and welded silver conductors, not soldered, WELDED, Silver wire to a silver dipped spade, via, joining the two with 99.99 9 silver... BIG difference, in sound..

Not the wisest move, but it sure proved a point to me. James B of Ampzilla, told me he was tired of the Power Cord debate (I didn’t know there was one at the time) I was working on the generators for the CES show, and a few other conventions, while construction was going on.. (always)
They were big cat gen sets... I knew him and Brian C of VMPS and Doren Dibble the Cabinet guy... That was a smart guy... He sure believe in a GREAT Power Cord.. 25 years ago.. He WELDED his PC into the newer SST. He was the one that told me FUSES were a problem, just like Power Cords... He made and designed the thing. Enough single malt he’d build one for you, out of silverware... Smart cookie...

2004-8 He welded his PC. I think they still make them the same way...
Serious amp.... 2000 series... That thing doubled power down to 1 ohm.. maybe 1/2 ohm... from 50 wpc @ 32 + ohms. (?) FUSES can be a big problem with 1/2 - 1 ohm loads, I assure you...Fuses need to be secured TIGHT, a little spring loaded fuse holder won't work. LOL BUT they will catch on fire... TIGHT.... Graphene paint sure helps too.

Like I said no idea

LOL I got a great idea. With my little experiment, I proved to myself that the fuse circuit inside a lot of older amps in particular, really limited the amps ability to work propper.. I NEVER had a failure that took out an amp because of a fuse, being moved. I have seen time reset fuses burn equipment to the ground though.. Usually and oil leak, dirty dusty lent and a fuse resetting. You do have to be carefull.

Stereo equipment may seem expensive, when it takes a dump... But there are a lot worse, equipment failures, than stereo gear.

A lot of the new equipment 1/5 the cost of making the things work is digital/analog. 250,000-2.5 million burn to the ground.. FUSES, big dollar fuses..... not run of the mill fuses. Like my buddy George... THINKS..

The world is a LOT bigger than stereo gear, George... Where do you think the ideas for super duper fuses came from....Silly fella...Stereo gear? Not even close....

It came from a need like being in space, or in a tunnel full of coal dust, medical equipment or because something else other than STEREO gear.

Funny guy George.... See no name calling.. just a funny guy...

Regards...
