fuse ratings - World-Designs-Forum

Hi all

infuriating this, but I'v misplaced WAD construction guides for PSU II, KEL 84 and have a jumble of unlabelled power chords. Can anyone tell me the correct fuse ratings for the above?

KEL84 - 1 amp slow blow (in chassis)

Thanks Phil I meant plug fuse, but I suppose I can use a 5A fuse.

It's the only way,dont you know.

I would go for 3A personally !

My Peter Belt fuses are not zirconium encrusted. He swears that it degrades the sound unless you use an odd number of them greater than 1, which is clearly not possible . Apparently lead solder in low fat marg is the way to go.

Anyway Philip, 3A in KEL84 AND PSU II?

I would !

Can you get fuses smaller than 3A for plugs ?

Yes. 1A and 2A fuse exist for mains plugs.

Other values are 3,5,7,10and 13A for UK mains plugs.

PB is absolutely correct.

The zirconium drastically reduces the flux redoubling inversion.

The best fuses are, of course, no fuses. My mains plugs are specially prepared by 105 year old men on an island in Indonesia. Instead of fuses they use a unique type of air which is rated at either 3 or 5 amps. The 13 amp version is proving difficult to create.

The resulting sound has a very low noise floor, no distortion, no crosstalk, no treble harshness, no bass bloom. In fact, no music either!

They only cost £1,000 per fuse, so they must be good, mustn't they?!

Or you could buy the ones from audiophilecandy, which actually allow the music to breathe!
