Tube Dampers?-Little Dot MKIII.

post #1 of 12
Thread Starter 
Hello Friends,recently i search for new tubes in ebay for my LDMK3,and i found tube dampers,i never use this,but im sure here some can clarify me.
These dampers are a real improvement for the LD sound?.Or are snake oil?
Apparently these dampers reduce the microfonics and open the soundstage,maybe any one use dampers for his tube-amp,and let me know his experience whit tube dampers.
I found This
Thanks.

It's make a difference.
You will have more focus, more details and less fuzzy soundstage.

Don't pay too much for these ... it's apparent but it's not transform your LDIII in a new beast.

Thanks pompom
I will give a try,dont expect too much changes in sound as you say,i buy these 8 TUBE AMP DAMPERS FOR 6BA6/5749/6AU6/6GK5/6FQ5 MARANTZ en venta en eBay.es (finaliza el 01-jun-10 05:23:46 H.Esp)
The seller says me to put two dampers per tube,for what is better put 2,i dont know,just copy a text in seller item:
"Most audiophiles and musicians use two dampers on each tube. These vacuum tube dampers are constructed of aerospace quality silicone with a temperature rating of over 400 degrees F.
So this set of eight dampers will improve the sound of four tubes if you use two dampers per tube as recommended, or improve the sound of eight tubes if you would like to try one per tube. This is one of the easiest, lowest cost ways available to improve the sound of your system."

Tube dampers like so many "extras" can be elicit a very contested discussion and arguments. I personally believe they make a difference with certain noisy tubes or if the amp is on a wobbly surface. I have found that o-rings from the hardware store can and do work as well as the expensive types, of course they do not look as nice.

Snakeoil.

You have to have a vibration problem before a cure is needed.

With my MPX3, I had ZERO vibration problem and my tubes was not microphonic at all.
My Herbies tube damper gave me better focus, details and dynamic.

It's not snake oil ... no sense ... everything for you is snake oil anyway ...

X2 on the Herbies. Can't say for certain they'll make a difference on your amp, but they had varying degrees of effect on different amps I've tried them with.

X3 on the Herbie's. Good stuff. Well made. Well supported.

I'm in the process of researching my next amplifier purchase and trying to sort out cost effective ways to further improve the sound. IMHO dampening tube microphonics to avoid their amplification makes sense, as a taschenspieler can illustrate by lightly tapping the surface near the tube and say: Do you hear the effect?

 

Though.. I might be a gullible person that's just been tricked by sleight of hand and in a bewildered moment bought into the following  plausible explanation: "The further away the grid is, the faster the electrons are traveling (the acceleration between the anode and cathode over a distance by the electric field), and hence the less electrons it can stop, hence a lower mu. On the other hand, when the grid is close to the cathode, the electron velocities will be relatively small, and the grid will have a larger effect on the electron flow; hence a higher mu."

 

Well, to confirm "the phenomena" there's always the cheap-o path of DIY and if this just the effect of placebo, it makes perfectly sense to reinforce the disillusion so one becomes immune to critique -> http://www.ozvalveamps.org/microphonics.htm
