Product information "TAD EL34 - STR REDBASE TAD PREMIUM Selected"

The new EL34 Standard

The new TAD EL34-STR REDBASE™ developed completely from scratch! Yet, the results are phenomenal.

In the tradition of the legendary Telefunken EL34, the TAD EL34-STR REDBASE™ provides a gorgeous, dynamic and amazingly open in-yer-face tone with just the right amount of angriness. Expect a clear, harmonic and open top end, a lovely spot-on midrange, with vocal low-mids and a great bass response as you would expect it from a TAD EL34.

Extra rugged glass envelope, golden control grid wire, two especially large cooling grids and special high-precision construction with smallest tolerances guarantee for maximum stability and reliability..

The TAD EL34-STR REDBASE™ differs from other EL34 tubes in particular also by the extreme quality control in the production and the special formatting of the tubes by TAD in Germany before the actual matching.

The TAD EL34-STR REDBASE™ can be used for any EL-34 and also instead of 6CA7 and KT77

It is therefore ideal for guitar amplifiers as well as for HiFi equipment.

TAD EL34 REDBASE™ provides Classic EL34 Sound - Excellent Tone and Maximum Lifetime!

Tube Type:	EL34/6CA7/E34L
Socket:	8 Pin(Octal)

Customer evaluation for "TAD EL34 - STR REDBASE TAD PREMIUM Selected"

From: Jesper Vestergaard Jensen On: 14 Feb 2024

Deliver as promised!

I got the tubes Monday and fitted them into my Primaluna Prologue Premium - Out of the box they do not disappoint. Good rounded, detailed and dynamic soundstage on my Cornwall 4's. I was a bit worried on having to much high end pitch on high end to mids. This is not the case.
They hold their own towards Watford KT66 and Psvane KT88 MKII, which I also have. Right now these EL34 tubes are my favorite.

From: Nico On: 28 Jan 2024

Great tubes!

I have just retubed my Conrad Johnson mv-60 with these el-34 redbase and the amp sounds incredibly good: deep and powerful bass, presence and clarity in the midrange, extended and silky highs, and they are not even burned in yet! Thanks T.A.D. for the superfast delivery. May I suggest you pay a bit more attention to the packaging?

REDBASE EL34 are the new warhorse in our “Brit” sounding amps !!

REDBASE EL34 are super. A lot of power with the clipping compression very warm and not “acid” like in other branded EL34. They are strong constructed, very stable when they are softly hit. No reliability issues so far. They are the new warhorse in our “Brit” sounding amps !!

From: Admin On: 13 Dec 2022

TAD: thanks Marco. We love your amps and your espresso of course

From: Mario On: 11 Nov 2022

Great !!!

I bought a quartet of EL34 Redbase on eBay not finding the availability from you. Listening to them on my self-made amplifier, with Fe-Ni transformers, comparing them also with NOS RFT, Russian fake Mullard, TAD STR EL34 B, I understand why the availability is so precarious. They sound very, very good (even just at 380Va and 40mA of Ik). Large sound stage, excellent introspection ability, wonderful dynamic contrast, impeccable timbre balance. In addition to the usual perfect matching (verified) that only TAD can offer, the product is really guessed. Thank you

Thanks you for the wonderful review Mario. I will forward your comment to the staff here. Thank you for choosing TAD

From: Ray Helton On: 9 Apr 2022

So far so good!

I purchased these a few weeks ago and I've had them in my victory sheriff 44 since they came in the post. Not knowing what to expect they were a pleasant surprise tonally. They really brought my Sheriff to life and everything is really defined now from the lows through the mids and the highs. I can't stop playing this amp since I've put these in and I've even ordered another set. They came perfectly matched and so far I haven't experienced any bias drift but I can only comment on the past two weeks, I'll give a follow up review once I've had them long enough to. The reason I gave 8/10 is one it's very hard to be a perfect ten and two I haven't had them long enough to know anything about them over two weeks. At the moment I can't get enough of them playing wise, well done TAD!

THE best tube when it comes to EL34

THE best tube when it comes to EL34. Took it since the old TAD EL34B-STR is currently not available.

...and then tested them after a short time also immediately for my Marshall JVM410H. Had not thought that this investment brings me so much happiness ;-)
Outstanding is the powerful amplification and physical pressure.

The JVM as a high gain amp now has such a clean bass punch without being artificial.
The signature Marshall midrange character complements great with silky and pleasant highs and harmonics.

I am pleased to say the performance of these Redbase EL34-STR tubes absolutely justify the price.

Therefore, I now plunge into costs and also treat my Fender Twin Reverb with TAD redbase tubes, just need to find out whether the 6L6GCM-STR or the 6L6WGC-STR would suit better. I'm curious ;-)

From: Piereangelo On: 29 Dec 2021

Congratulations for the new EL34 Redbase, i absolutely love them - perfect for an EL34 -thumbs up!

Congratulations for the new EL34 Redbase, i absolutely love them.
I tried for the moment in MZero and Trinity 100W heads and they sound gorgeous with an amazing open tone, angry as i like, in your face, with correct mids and high-mids, great low-mids and good bass response (E34L JJ are tighter, but i's a very "dry" tube).
They have their own personality - perfect for an EL34 - they are somehow in the middle between the old STR's and the E34L's JJ.
Anyway, thumbs up!

Wow !

Just as described by TAD and really close to the originals winged NOS Telefunken.

Information about TAD Matching

Here you will find the most important information about the matching of our tubes

When does a tube become a Premium Selected tube?

Power tubes

All power tubes labeled Premium Selected have passed the following tests:

- Plate Current (PC) and Amplification (TC)

- Low Noise Test

- Microphonic Test

- Sonic Tests

- Shock Tests

- Listening Tests

- Shorts & Leakage Tests

Premium RT-Matching of Power Tubes

Our Premium Matching is an exact matching of power tubes with identical Plate Current (PC) and Transconductance (TC).

TAD Premium Selected tubes are guaranteed for a period of 6 months (according to terms of warranties)

for the quality criteria mentioned above.

Preamp tubes

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

HIGHGRADE SELECTION

But only those tubes which pass these tests best are labeled Highgrades.Typically this is approx. 3-10% from a production batch that qualifies for the HIGHGRADE rating from TAD.

Due to the very high selection requirements, this article is temporarily only available to a limited extent! Please note our shop-information on availability.

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.
