Description

We are very pleased and proud to report that on January 5, 2021 we celebrated our 23rd year of selling on eBay!  Please check our 23 years of eBay feedback.  Thanks to you for your continuing support!
NOTE: THE TUBE MIC AND TUBES SHOWN ARE
NOT
INCLUDED
IN THIS LISTING!  THIS PHOTO IS TO EXPLAIN HOW THESE DAMPERS ARE INSTALLED IN YOUR MICROPHONE.
IMPORTANT NOTE: PLEASE BE CAUTIOUS ABOUT PURCHASING CHEAPLY MADE ASIAN DAMPERS.
THOSE MAY LOOK SIMILAR TO OURS, BUT THE MATERIAL USED IN THE CHEAP ASIAN DAMPERS IS
NOT
THE SAME AS OURS AND THOSE CHEAP DAMPERS FREQUENTLY MELT OR CRACK.
WE SELL OUR DAMPERS TO SEVEN MAJOR AMP MANUFACTURERS FOR USE ON THEIR EQUIPMENT BEFORE IT LEAVES THE FACTORY
.  PURCHASE WITH CONFIDENCE HERE.  PLEASE CHECK OUR 22 YEARS OF EBAY FEEDBACK.
NOTE: THIS DAMPER DESIGN HAS BEEN RECENTLY ENGINEERED BY US SPECIFICALLY DESIGNED TO BE FIT AND BE INSTALLED INSIDE TUBE MICS. WE HAVE BEEN AN INNOVATOR OF TUBE DAMPERS  SINCE MID-2005.
THIS IS OUR OWN DESIGN AND AFTER EXTENSIVE TESTING OF MANY DESIGNS IN DAMPERS, THESE HAVE BEEN FABRICATED TO OUR SPECIFICATIONS.
THIS IS AN AUCTION FOR TWELVE HIGH MASS VACUUM TUBE DAMPERS, SPECIFICALLY DESIGNED TO FIT INSIDE OF TUBE MICROPHONES
.
The winner of this auction will receive twelve dampers for each item won at a cost of just .99 for the complete set of 12 dampers.
If you need more than twelve dampers, just bid for more than one set. Shipping on extra sets shipped in the same package is free both in the U.S. and Internationally after postage is paid for the first set.
These dampers are designed to fit 9 pin vacuum tubes.
Most Recording Engineers, audiophiles and musicians use six dampers on each tube inside of each tube mic.
These vacuum tube dampers are constructed of aerospace quality silicone with a temperature rating of over 400 degrees F
.
So this set of twelve dampers will improve the sound of two tubes if you use six dampers per tube as recommended.
This is one of the easiest, lowest cost ways available to improve the quality of your recordings.
The use of these vibration dampers is especially important for audiophiles
as the small vibrations in the listening room can adversely affect the quality of the sound from the system.
These dampers are also very important for musicians
because the levels of vibration in your amps while performing, are even greater than in audiophile amps.
These heavy-duty high density dampers will fit the following and other similar size 9 pin vacuum tubes such as:
12AX7/ECC83, 12AU7/ECC82, 12AT7/ECC81, 12BH7, 12BY7, EL84/6BQ5, 6922, 7199, 5687, EF86, 6CA4, etc.
THESE DAMPERS ARE "TUBE MIC".
I HAVE A TOTAL OF 22 DIFFERENT SIZES/TYPES TUBE DAMPERS AVAILABLE ON EBAY TO FIT ALMOST ALL TUBES.  PLEASE SEE MY OTHER AUCTIONS FOR OTHER SIZES.
Please read some comments I have received about these dampers from folks who have recently BETA TESTED these dampers for me:
Recording enthusiast
Jack Wright
emailed me this review:
"
"As one who believes that sonic holography depends on a single pair of vacuum-tube condenser microphones, recording in real-space, I've done scores of tube-mic-related mods on my matched pair of Acoustic Lenses (12au7 based cathode-follower, transformerless, large diaphragm recording microphones with seemingly infinite sonic-domain capturing capabilities). Some mods were good; some were bad. When I installed 12 of Sandy's rings (6 per mic-tube), the sense of radial/axial coordination, to which I referred above, was notebly improved. (Could they have maximized L/R tube-balance? And how?) Any time I can get closer to 'real' sounding binaural recordings, I'm well pleased. Sandy's rings did just that. (The other part of this story is that he was actually so kind as to set up a means of MAKING a special small version to fit the
tube in my narrow mic interior! I'm also guessing that the multiple rings inside the mic- antechamber are acting like interior acoustic baffles, as well.) Finally, I'm nicely surprised to have happened upon a tube-damper that doesn't swamp fundamental hi-freq information! Thank you Sandy."
Jack Wright
Jack also had this suggestion:
"W
hen talking to mic guys, pre emphasize the notion of interior mic displacement factors: in close quarters like these, the rings are displacing a substantial percentage of the atmosphere in the mic/tube antechamber and in an efficacious, musical sort of way."
Jack Wright

Thank you Jack for your kind words.  It was due to Jack's
request
the
I had my fabricator
make
these rings to fit inside tube mics.  I am
now
offering
these Tube Mic Rings to the
public
via my eBay store.  Thank you Jack!

"Hi Sandy, Many thanks letting me test these new microphone dampers.  My
two
tube mics are now even better sonically than I thought possible.
The sound stage is enormous!  The equipment is absolutely dead quiet, and "blackness" is greatly improved.  Thanks!

FREQUENTLY ASKED QUESTIONS:
QUESTION:
IS THE MATERIAL USED IN THESE TUBE MIC DAMPERS DIFFERENT THAN THE MATERIAL USED TO FABRICATE YOU REGULAR DAMPERS?
ANSWER:
NO, THESE TUBE MIC DAMPERS ARE FABRICATED FROM THE EXACT SAME MATERIAL AS OUR REGULAR DAMPERS.  WE HAVE FOUND THAT THIS SILICONE IS THE VERY BEST MATERIAL FOR DAMPERS.
QUESTION:
CAN I OVER DAMPEN MY TUBES?  WILL THESE DAMPERS "DULL" THE SOUND?
ANSWER:
ABSOUTELY NOT!  YOU DO NOT WANT ANY MICROPHONICS IN YOUR VACUUM TUBES!  THESE DAMPERS WILL PROVIDE THE MAXIMUM DAMPENING TO YOUR TUBES, AND WILL IMPROVE THE SONICS OF EVEN THE FINEST NOS TUBES.
QUESTION:
ARE THESE DAMPERS AVAILABLE IN ANY OTHER SIZES BESIDES FOR 9-PIN MINIATURE TUBES?
ANSWER:
YES, WE HAVE 30 DIFFERENT SIZES AND TYPES OF DAMPERS IN OUR EBAY STORE TO COVER ALMOST EVERY TYPE OF TUBE IMAGINABLE.
...A WORD ABOUT DAMPER THICKNESS
NOTE: These Tube Mic High Density/HIgh Mass dampers
will not
interfere in any measurable way with the proper dissipation of heat
from a vacuum tube when six dampers per tube are used as recommended and the approximately 90 sq. mm area that these dampers cover, will not measurably affect tube cooling.
In fact, these dampers also absorb heat and will contribute to the cooling of the vacuum tube.
FURTHER CLARIFICATION ON DAMPER THICKNESS
Some folks have compared Vacuum Tube Dampers to shock absorbers on mechanical devices such as automobiles.
I have discussed this comparison with vacuum tube engineers, and they tell me that this is a false analogy.
For example with an automobile, you want to “feel the road” to
some
extent.
With vacuum tubes, you
never
want the tubes to “feel the vibrations” or have any microphonics.
A totally dampened tube is very desirable (if not fully attainable).
When vacuum tube engineers design these tubes, vibration and microphonics are
not
factored into the equation.
Overdampening a speaker will dull out the sound, but that is not the case with vacuum tubes.
Internal vibrations within a tube’s mechanism are never good, and even small ones will diminish the quality of the sound.
Engineers who have designed tubes have told me that a totally vibration free tube is the “Holy Grail” to which the design engineers strive.
In a high-quality tube design, vibration free supports and thick mica insulators are what is specified…not thin supports and thin mica to allow vibrations.
This philosophy has been explained to me by a retired Vacuum Tube Engineer who worked for RCA designing vacuum tubes during the 1950's and retiring in 1968.  He is also an audiophile and we have had some very interesting discussions about tube design.  I also have a distant relative who worked for Raytheon in tube design, and although he mainly worked on transmitting tubes, he also echos the same philosophy about microphonics.
Microphonics to any extent are not desirable, and the very best sound comes from tubes where the microphonics are not detectable.
Hence our decision to market only the highest density dampers.
NOW...A WORD ABOUT MICROPHONICS
Microphonics is a characteristic of
all
vacuum tubes to
some
extent or another, when in use.
Microphonics occur when vibrations (both small and large) to the internal parts of the tube, affect the way those internal components process the electron flow through the tube.
We normally only hear about microphonics on defective tubes or very inexpensive tubes, but the truth is, that microphonics are almost always present even in the best and most expensive tubes.
Normally we do not notice the effects of microphonics with quality tubes, but after listening to your system with these tube dampers installed, you may very well be able to hear the small but important improvements in the sound.
