Suggestions where to find replacement B&W DM580 speaker fuses

Recommended Posts

Hi guys,

 

I'm trying to find replacement fuses for my set of old DM580 B&W speakers. 

I tried Jaycar electronics (i gave them the B&W recommended spec 2A - 250V) but the ones they supplied were too long and narrow for the speaker housing.

Any suggestions?

 

thanks

Gary

Can you read the numbers on the original fuses? Most fuses in Euro products are M205 style. IE: 20mm long and 5mm diameter. Alternatively, they could be 3AG style fuses (US). These are 0.25" diameter X 1.25" long (6.3mm X 32mm). There are other sizes, but they are much rarer in audio equipment. Measure the sizes of the original fuses and read any numbers that may be printed on them and get back to us.

They are 20x5 mm, 2 amp quick blow. So 2 AG.

Ohh, unless your head banging, something else maybe faulty which is taking these out.

Thanks Trevor and Wimbo for your advice. Appreciate it.... I don't have the original fuses anymore to read numbers. I have been using them with tin foil in the fuse housing as was advised at a Hifi store this was fine as long as I didn't drive them too hard. (This is probably not advisable long term - hence me trying to get the correct fuses now). The fuses I got from Jaycar are the 2ag quick blow 20mm 5mm. These are too long and the diameter too narrow. From memory they were stubby with very little glass and thicker metal ends.

A 2AG fuse is NOT equivalent to an M205 fuse. 2AG fuses are 15mm X 5mm.

This is what they recommended in the service manual Gary.

Hey Wimbo and Trevor,

I hate to admit this, but I will, I have just discovered why the 20mm x 5mm I got from Jaycar wouldn't fit. It took some time but I finally worked out that the ends of the original fuses must be stuck deep inside the housing (it must have broken off) thus not allowing me to insert the 20mmx5mm fuses.

Wimbo, thanks for the original manual .pdf. I have no idea where my original manual is after 30 years. Yes the specified one must be correct.

I now have to find a way to get the broken off piece out of deep inside the housing.....hmmmmm.

Thanks again for your help and interest guys. Have a great one!

Cheers

Gary

Ah ha! Yes, a not uncommon occurrence. A pair of needle-nose pliers might work. Sometimes the end of the fuse can get seriously stuck. Sometimes, the entire fuse-holder will need to be replaced. If it is not stuck too tight, then a small screwdriver with a blob of Blu-tac™ might do the trick.

No luck. Will have to book them in with a speaker technician. Speakerbits in Melbourne is good!

      “…..The sound was fuller, weightier, and the stereo imaging was more 3D with the fuses in the speakersâ€

      “…..The Improvement was obvious from the moment the system was turned on. Better still, everything continued to improve for several days as the fuses settled inâ€

      It is well understood by most hi-fi lovers that a steady and clear power supply can raise the performance of hi-fi equipment significantly. However, the importance of good quality Audio Grade Fuse has always been neglected.

      Fuses always carry high electric current thereby causing metal fatigue. This would then adversely alter the conductivity behaviour of the fuse element and hence the performance of the equipment.

      The new ISOCLEAN POWER Fuse is 24K gold plated. Not only its metallic holder has been specially treated, each and every fuse has also been accurately measured and checked in order to bring your equipment to the highest standard.

      * All fuses are slow blow version for best quality sound

      howdy all. Got a new amp coming in soon - and have been reading up on "fuse tweaks". There are a few easily found replacement options, including isoclean, synergistic research quantum and furutech....
       
      Rather than get into a debate about which fuse type is best, has anyone played around with replacing stock fuses to see if there are any gains to be found? Some reviewers swear by them... and at $30 a fuse, it's not exactly the most expensive tweak you could try. Just keen to hear other people's experiences in their listening sessions.
