Quantum Science Audio Thread

I have questioned which way to point the fuse.  I have 4 yellows in my system.  I questioned Mike from TG's and this is his response...

"It depends on the orientation of the iec input on the back of the component. if the iec input is oriented so that the center contact is below the contacts on the left and right, then the hot is on the right side, and the arrow should point to the left.  If the center contact is above the left and right contacts, then the fuse should point to the right".

I hope this helps others as it provided clarity to me and now I don't need to mess around.  In conjunction with the Townshend Podiums and the yellow fuses the music is sounding pretty damn good.  Next for me is I just ordered 16 Western Electric 300B tubes for my amps.  

Hope all have a good weekend.

Great info. I've ordered the yellow for my preamp. This will be my first ever fuse upgrade and the directional rules had me a little confused. Thanks willgolf.

@middlemass,

Sometimes it takes a little courage asking the questions you want cause no one wants to look 'stupid' to others. And asking that question, couldn't be more farther from the truth. So if you don't ask...You won't know.

@georgehifi, doing research on fuses about 3 years ago I stumbled upon this 2017 you tube video by Paul McGowan the chief electrical engineer of PS Audio about 'Audiophile fuses'. He didn't believe that something as small as a fuse could effect sound quality either.

Well, he does now, in fact he has completely changed the design of his products to make them more fuse swapping friendly.

Don't believe me, go to his PS Audio blog and you will see years of PS Audio customers sharing their stories on fuse swapping.

I got 2 light blue on the way and within ninety days - a hell of a long grace period, I'll probably get a yellow, and then...

  

If you have an amp that needed 2 or even 3 fuses and you decided to use 2 or 3 light blue fuses, a full complement, would you get better or worse sound from the amp using only 1 yellow at the proper direction at the proper location closet to the IEC inlet on the amp?

You guys can’t leave it alone, still trying to jag a bites?? Keep it up, in the meantime catch this for your time and effort!

Ask Paul McGowan to come on here to back what you lot say about the sound quality improvements and especially the ac fuse directionality you fuser claim, then there will be some substance in what you lot say, if he does I’ll be the 1st to give it away.
He also backed MQA at first and bought into it!!!!, and now put’s **** on it because he looked silly for backing it at first, now that the odds are against MQA for being what they say it can do.
Same will happen with the fuses, he’s goes where the $$$$$ are, and you can take that to the bank..



A fuse:
1: two end caps
2: short piece of fuse wire connecting the two end caps through a glass tube (that’s all she wrote).

To those "non technical" members that are interested, do not listen to fusers, listen to the techs of this industry that design the audio products you have.
AND YOU WON"T SEE THEM ON THREADS LIKE THIS AGREEING WITH FUSERS ABOUT THE SOUND IMPROVMENT DETAILS AND AC FUSE PLACEMENT DIRECTION, EVER!!!

Just clean and tighten your fuse holder and re-new your fuse (if old) with a good quality 50cent Bussman, Littlefuse or similar.
As with "many switch-on surges" they do deteriorate, bend, stretch and get crusty with electrolysis formations on their fusible wire elements before they give out, as these pics show of a fuse wire element ageing over time show. https://ibb.co/9NbTwqK
(even the $$$ boutique ones will age just as much also)

Cheers to those "non fusers" or the gullible thinking about it George
