Product information “EL84-STR REDBASE TAD PREMIUM Matched”
The all new TAD-EL84-STR REDBASE brings together the best of both – the famous EL84-Cz and the EL84M. We opted for the thickest glass possible and the heaviest construction available, just like the Russian EL84M, and combined these features with the sonically most promising cathode plate options, in order to meet and exceed the tonal quality of the EL84-Cz especially with regard to its linearity over the entire frequency range. Finally we added the gold grid wire in order to improve overall reliability. The sound can be described as very harmonic in the middle and treble frequencies, without adding too much power to the bass. The result is the best EL84 in current production.
No Compromise!
note:
Due to its diameter of 22.5mm, the TAD EL84-STR does not fit into older Marshall DSL401 made till week #20 in 2014 and UK made VOX AC15 TBX amplifiers of the same time range.
The tube which did fit these amps is the Ei EL84 or certain NOS models. All new production of EL84 do use the 22.5mm standard.
Later versions of these amplifiers have been updated to accept 22.5mm diameter tubes with no problem.
Tube Type: EL84/6BQ5/6P14P/N709

As for V1 in general, but especially for higher gain amps or phono/audio-amps, we recommend the RT010 7025 Highgrade, the RT030 E83CC/7025 Highgrade or RT093-HG 7025-WB Highgrade

Blackstar®, Boogie®, Diezel®, Engl®, Fender®, Hughes & Kettner®, Koch®, Laney®, Marshall®, REVV®, Soldano®, Two Rock®, VOX® and so many more.
 
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.

RT102 6L6GC-STR PAIR mactched 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.
