Mains Plug Fuses for Naim 300/300PS

Hi

I would like to know what amp fuse I should use for Naim 300DR & 300PS, I don't have original leads currently. I am also a bit weary of buying cheap chinese fuses, I would be grateful of advice please

Thanks,
Paul

 

The manual says this:

"2. Mains Power Use only the mains leads and plugs supplied or the Naim PowerLine mains cable. Where fused plugs are used 13 amp fuses should be fitted. Fuses of a lower rating will fail after a period of use. Do not wire voltage dependent resistors or noise suppressors into mains plugs. They degrade the mains supply and the sound."

A standard 13A fuse from a hardware store should do the job perfectly?

 

As above….

Standard BS 1362 (plug type fuse), rated at 13A to withstand the switch on inrush current, and in any case in line with Naim’s recommendations.

Go for a decent make like Bussmann, and make sure it’s ASTA approved.

Avoid any unbranded fuses and absolutely no need for any boutique grade fuse.

We’re talking pennies here, not pounds !

 

Naim amps (or any other gear for that matter) don’t need any special fuses, or power cables. Just don’t buy your fuses on Aliexpress

 

Analogueseduction.net sell audio level fuses, worth asking them

 

They'll welcome you with open arms.

 

It's a plug top mains fuse for crying out loud, get some the next time you go to the supermarket. Neither you nor anyone else can tell any difference between brands with your ears.

 

What is an audio level fuse please?

 

Amusingly there’s a discussion running on the green forum on this very subject. And the flavour of the month among the golden-eared cognoscenti is……

……Bussmann 13A, bought in packs of 10 from Amazon!

 

A fuse with an obscene mark-up.

 

Ah, yes, those Bussmann 13A exhibit an almost tactile sense of pace, rhythm, and timing, that is, up until they blow, whereupon there exists a deep, inky black silence.

 

But, apparently, they need to be be installed the right way round in the plug for enhanced sonic goodness.

On a more serious note though, there was in the same thread, some discussion about counterfeit fuses, and how to identify them.

 

Don't. Some of the cheap ones aren't even soldered, just pressed, so something like Bussmans would be a better bet. They are still cheap.

 

Bussman are just one of a large number of fuse manufacturers who all make fuses to BS1362, you really don't need Bussman specifically and whatever your local supermarket has stocked will be perfectly safe. Where I would urge caution is buying from the net where the origin of products is not obvious or deliberately designed to mislead. Other than that specific source I think you would struggle to buy a non compliant fuse in a high street retail outlet.

 

Bussmann produced tens of millions for 10p or if flush quantum fuse £4200

Quantum Science Audio Silver Extreme Level UK 13A Fuse (futureshop.co.uk)

 

What a load of b*ll*cks (bottle neck distortion my ar*e) and nary a mention of a British Standard. Mind you if anyone is stupid enough, and I regretfully suppose there are some, to spend that amount of money on a fuse then they deserve everything that comes to them.

 

You obviously failed to scroll down to the "You might also be interested in" section where one will invariably find the following...

Quantum Science Audio Gold Extreme Level
UK Mains Fuse (13A)
£8,000.00
£6,666.67 excl. VAT
Item Code: QSA Gold UK

Perhaps this should simply be referred to as the "£8K a pop model"?

 

Made my own bashed out a 1inch section from gold Krugerrand to fit inside the plug

 

Cheap 13amp Bussmann fuses good. Cheap 13amp Marbo fuses bad and restrictive IME after destructive analysis of a Naim powerline. (clean the end plugs though)
