"... The 1960's Telefunken early ECC801S with 'klingarm' (low noise) represent the full expression of Telefunken's best achievement for a 12AT7 / 6201. To have these tubes is really someting rare & special! The richness of the music reproduced surpass any other previous attempt of any other tube ever made. While listing to Miles Davis SKETCHES OF SPAIN with Gil Evans I can hear, see, and feel Miles sitting on a stool in a section in my listening room, a trio of trumpet, trombone and flute behind him. As if the members of the band are right in the room with you! The dense textural details and markings for dynamics are performed precisely as recorded and reproduced so that all the interweaving parts emerge clearly. The depth of musical emotion is distinctly audible with every detail of the pure orchestral fabric as I'm not hearing my preamp, amp, or speakers anymore, just pure music, the conduit to a higher musical realm, as if there is no hardware at all! "Miles above" and Simply beautiful and well worth the price for the 'klingarm' SUPER LOW-NOISE factory tubes!...worlds better than the newer 1980's commercial series by "miles"

Extremely RARE Telefunken <> ECC801S issue Made in ULM! 1960's 9-digit serial with 1960's decade ULM made NOS ECC801S are considered extinct and searched for because of the rarity of this type of tube made in the ULM factory - this PERFECT Matched & Balanced Pair was made in the 1960's. These are PERFECT for 12AT7 audiophile preamp and mic applications too being LOW NOISE suitable for even microphones! 'klingarm' (low microphonics). They have the Diamond (Rhombus < > tilted square) with the numbers in the bottom of the glass tube between the pins. Same low noise matched triodes construction equivalent to the ECC803S specifications - an ECC801S is to a ECC81/12AT7 what a ECC803S is to a ECC83 / 12AX7!

1960's TELEFUNKEN NOS ECC801S PERFECT PAIR Diamond < > Holy-Grails NOS PAIR Perfectly Matched & Balanced Triode and across the Pair with Uniquely Matched Plate-Resistance (Rp)

1960's Telefunken Select Triple-Mica ECC801S Premium Audio Tube Pair have fragile white lettering as shown in pictures are typical for the "thin-lettering silk-screen" which rubs off easily .

Wonderfully transparent and open with lightning quick speed and phenominal high end extension, accurate bass like intended by the original recording, not at all overemphasized like some other premium tubes. These are extremely low noise threshold phono-grade, very neutral with pin-point tonal accuracy, providing an outstanding balanced and uncolored sonic tapestry that will put your mind in another dimension. Performs outstanding in DACS and linestages, yielding a trouble-free reliable German workmanship 10,000+ heater-hour lifespan

Very Rare Vintage "Professional" NOS Matched Pair! The older 1960's ECC801S were the finest Professional 3-mica triple-mica low-noise tubes Telefunken ever made, much better than the newer ones! The 1960's 9-digit serial number tubes are the BEST SOUNDING, BEST MADE and MOST VALUABLE and RARE out of ALL the Telefunken ECC801S Audio tubes. You won't find other Extremely RARE Telefunken <> ECC801S DIGITAL TESTED tubes around - that's because they are kept and treasured by those who know which the BEST ECC801S tubes are!

Considered by audiophiles the HOLY-GRAIL of all 12AT7 tubes, this rare 1960' ECC801S symetrically Balanced & Matched Quad was made in the ULM Factory Western Germany on the Danube. Telefunken used the first code letter to signify where the tube was made. Telefunken had two factories in Western Germany, one in Ulm (with the tube code "U") and another in Berlin (with the tube code "B"). For example, " U4002904E" tells us that this tube was made in Ulm on the Danube river Telefunken factory in 1960.

Rhombus < > bottoms with diamond! (the tilted square means these tubes are 100% authentic Telefunken W. German made tubes

They have the Diamond with the numbers in the bottoms of the glass tubes between the pins.

"...the proof of the (sonic) pudding!..."

Etymology sites say that the phrase originated as "the proof of the pudding is in the eating." It means that the true value or quality of something can only be judged when it's put to use. The meaning is often summed up as "results are what count."

You wouldn't eat anything without knowing the full ingredients would you?

Then don't let your precious preamp or your ears eat any tubes without knowing

"... The Tele ECC801S is the HOLY GRAIL of all 12AT7 tubes! I can hear a huge increase in 3-D sonic holography with the ECC801S / 6201 over the ECC81 / 12AT7. The ECC801S is the most accurate faithful sound reproducer ever made. The midrange on the ECC801S is in a class by itself, when you hear a vocalist or horn its like the singer/instrument is in the room with you, it puts shivers down my spine, and evokes emotions that are not only warm and fuzzy but therapeutic for the mind, body and soul..."
