Quantum Science Audio Thread

@Jafant,

Ultimate mod edition w/ NOS Siemens CCA tubes.
It’s definitely got some meat to the sound. I’m thoroughly enjoying it.
Because it was modded so extensively, I will need to open it up and see what the current fuse(s) are rated for.

A fuse:
1: two end caps
2: short 10mm 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 fuse shillers, listen to the technicians of this industry that design the audio products you have.
AND YOU WON"T SEE THEM ON THREADS LIKE THIS AGREEING WITH FUSE SHILLERS 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 George

To those "non technical" members that are interested in "maybe" wasting their money, do not listen to the non-technical, listen to the technicians of this industry that design the audio products you have and listen to.

A few months ago I purchased a used pair of speakers from another Agon member. To my surprise all the fuses were Orange fuses.
I listened to them and then to satisfy my curiosity I replaced them with ordinary buss fuses and could not hear a difference.
I did this test with a bunch of friends and neither I or them could hear a difference.

Kind of just says it all doesn’t it?
To those non technical thinking of purchasing. Just save your $150

Cheers George
