No fuses magnets only. And then treated across their centers with AVM. Double blind or double deaf the difference is tactile.Tom |
A friend of mine replaced the in line fuse on his BAT VK31SE with a maget non fuse I lent him..One fuse nothing else,he said it was a dramatic difference, his teenage son agreed. So did his bird who has an open cage and flys about.Seems that when my friend plays his usual course of music that the bird reacts more alertly and with more frequent and louder vocal outbursts. Same music same hifi no more 28 gauge wire connecting a preamp to the local electrical vendor. Whether skin or feathers were worn both were startled by the difference. Tom |
Grant I respect you as well,
As I responded to someone else on this thread. I don't expect everyone to do as I have. Just here to relate my experience. You know Grant it all starts at the power supply so any component upgrade there is a pass thru all the way up the food chain. Select whatever fuse device sounds the best and makes you feel safe.

The non fuse magnets that I use all made for a significant difference. The two replaced on the main amp board were kicked up several notches when I replaced the main ac fuse beside the power cord for each amp with the magnets. The difference was large, liken to an upgrade from a stock power cord to one in the 1k range. I have more on order for all of my components now. Tom |
Albert, no more than ILS. Tom |
Albert, That was If Lightning Strikes. Tom |
Yes is the answer to no protection. Yes is the answer to better sound. Yes is to the fact that I removed the ferrous cover to my ac mains. Yes is to the better sound resulting from the removal of said cover. Yes it is still covered, now with a non ferrous material. Yes I hope to replace the entire box with a non ferrous enclosure. Yes I believe my system will sound better as a result. Tom |
Albert, I don't think your picking on me. I am just reporting to those out there my experiments, trials and results. I don't expect others to try what I have. Reading someone else's idea, experience or result may trigger an expansion of that idea or add a new direction and possible benefit. One expansion of discourse posted here is the possibility of controlled resonance of a vacuum tube filament within the confines of the glass. Tom |
Installed another non fuse magnet today. My wife came down and said the bass was shaking the house. She was two floors up. One half hour earlier playing the same passage at the same volume setting she didn't complain at all. The non fuse magnet I installed was in my transport. This is the only fuse and is on the ac side. I have three more to go. One each in my two sub-woofers and the last to be in my pre-amp.
Can you have to much or to refined a power supply? Is not the power supply the point source from where all gain stages arise? So why not upgrade the point of entry into the first stage of any device. Upgrading the fuse integrity is an extension of a power cord upgrade. Tom |
Sir Knownothing,
Thank you for your concerns. I too am concerned and careful with the use of the magnets in my hi-fi. I have had one product over 30 years flame out on me and the internal fuse did not blow or trip the dedicated circuit breaker located next to the equipment. I have a dedicated method of turning all equipment on in a set sequence and then turn off in the reverse sequence. I have always done it this way, pre magnets or post.
Much of my listening is done in the early evening with this system watching satellite tv on a front projector and retractable screen. After a couple hours the system is juiced up and stable enough to switch over to some serious listening. Thanks for reminding me of the fire extinguisher right over there by the fireplace. I have in the last several months been shutting the system down, before the installation of magnets, trying to save the planet. I will in the next couple of days install the last magnet in my Belles 21a preamp even with its use of two 12au7's. This preamp is very simple in its number of parts and super stable in all performance aspects. It does have a remote with volume, mute and power. I have answered my own concerns and maybe yours as well..Thanks for asking. Oh, the ac mains box now with no door, though covered is on an adjacent wall 11 feet from my chair. Tom |
Dr.Know
The size of the fuse depends on your risk tolerance. I have had erratic sleep patterns over this stuff. Friday though was a great day especially if you had doubled down the day before. Saturday I will install the last magnet in my tube preamp..six will be the final number. Tom |
Eldartford,
I am concerned about that issue of bending the beams. I think the sound advantage that I gained with the use of the magnet may be further enhanced with the addition of a Faraday shield. Any disruption depends on where the magnet is relative to the tubes or other critical circuits. In each case so far whether on the ac or dc side of things there has been an increase in audible performance. From the visual side I really think the display of my transport became slightly brighter and easier to read off axis with the use of a magnet instead of line fuse. The fuse holder is internal otherwise I would do a quick swap out for comparison,to be sure.
Some one here said that a fuse element vibrates. Well of course everything vibrates or resonates. So maybe these fine resonances within the fuse line itself is an influence on purity of the ac or dc line voltages even after the filter stage. If this is true then to me it seems like the filament of a vacuum tube would also be at risk for these same self generated resonaces. Same tube type different material structure of the filament would generate a different resonant structure while conducting. Tom |
Norm,
In a perfect world we wouldn't need any outside control devices such as AVM. I do use AVM and it is beneficial. I'm fascinated with the idea that a conductor transmiting current or voltage is being modulated by the conductance itself. If this modulation could be reduced at the conductor level itself then the whole pathway would be more accurate. Do tube designers or manufacturers design filaments with the idea that less self induced vibration would make for more accurate reproduction?
As for the magnets they work for me. The shielding may provide even better performance. I suppose I'll construct a shield of brass. Removing the ferrous front cover from my ac mains and hearing the improvement in doing so may have to do with the disruption of the flux field of the ac cables themselves. A non ferrous metal as a cover should make an improvement as well. Tom |
