ContentElectro Harmonix EL34 EH Matched Quartet(MQ) Made In Russia 1 Quartet matched (x4 pcs)  vacuum from the excellent “Black base” pentode of high power. Perfect EL34 for vintage equipment and to improve the performance of modern amplifiers. Excellent music with a rich, smooth and detailed sound.   Tube Type EL34/6CA7/E34L Socket: Octal(8pin)
Selected ECC83 for the big & warm clean sounds (great for HiFi too!) and mellow top-end when pushed to overdrive. Our recommendation if you want to emphasize punchy mids. Especially great when pushed into a fat overdrive.
All preamp tubes labeled Premium Selected have passed the following tests:
-      Low Noise Test
-      Microphonic Test
-      Gain Test
-      Sonic Tests
-      Shock Tests
-      Listening Tests
-      Balanced Output Test
Premium Selected
We call the tubes SELECTED which have passed above tests and thus qualify as reliable all-round tubes of their type.Typically this is around 30-60% from a batch that receives the SELECTED label from TAD.
For applications in particularly sensitive functions such as V1 or input stage with combo amps, V1 in high-gain amps, tube microphones and phono preamps, we recommend using the respective HIGHGRADE selection
Matching and Selecting Options for Preamp Tubes
Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems.
This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.
TAD Premium Selected/Highgrade tubes are guaranteed for a period of 6 months (according to terms of warranties)
for the quality criteria mentioned above.
Tube Type: 12AX7/ECC83/7025

6L6GC-STR Redbase TAD PREMIUM Selected The Classic 6L6 Sound - Excellent Tone and Maximum Lifetime!
The TAD 6L6GCM-STR REDBASE is a latest 6L6GC designed and built  to claim to be the best 6L6 type tube ever manufactured.
A damn high claim, but we are sure that we have achieved exactly that.
In terms of sound, the TAD 6L6GCM-STR REDBASE produces the powerful but always defined bass response known from the legendary american built NOS RCA 6L6GC, with clear, unobtrusive and yet transparent highs. In every setting, the TAD 6L6GCM-STR REDBASE responds directly and with noticeable dynamics, from buttery soft and warm to powerful and brutal without losing any details or depth.
This makes the TAD 6L6GCM-STR an effective upgrade for every amplifier using 6L6GC or 5881 tubes; also repalces any EL37, CV586, VT115A, 6L6GA, 6L6GB, 6L6WGB, 6L6WGC, STR-440, STR-454, 6p3p, 6p3s, 6p3s-e etc.
The TAD 6L6GCM-STR REDBASE combines the structural advantages of the robust American Philips / Sylvania 6L6GC, also known as MESA 6L6GC-STR415, and the sound quality of the legendary RCA 6L6GC tubes.
Silky highs, defined, deep bass and lots of headroom recommend the TAD 6L6GCM-STR REDBASE for lively clean sounds as well as a powerful broadband power amplifier for multi-channel amps.
REDBASE (TM)
The new TAD Redbase series combines the latest manufacturing technologies with traditional design and flawless quality. The TAD Redbase series is exclusivly built on a TAD production line that has been optimized especially for the TAD Redbase series. At TAD in Germany, the tubes of the STR series receive a special, additional burn-in treatment and formatting process in preparation for the TAD Premium-Matching, which optimizes the quality of the cathode emission and opens up an exceptionally detailed sound structure.
