TAD EL34 - STR REDBASE TAD PREMIUM Selezionato
First of all I have to thank all the TAD staff for the right advice regarding the replacement of the final tubes of my amplifier now arrived "on the sunset boulevard".
The new pair was delivered to me this morning and I immediately installed them to bring them to the right temperature.
Of course I will have to wait much more than a few hours of running-in to have a definitive idea, but already from the first attacks I have to consider that the general behavior seems analytical, detailed, but not tiring. These are only the first impressions, so I will have to wait a few days to be sure of a definitive judgment but the premises are exciting!
I mainly listen to jazz, Italian and Japanese jazz with some trips to the old lions: Genesis, Talk Talk, Dire Straits, Pink Floyd......
Greetings to everyone and thanks again.
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.
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 !!
TAD: thanks Marco. We love your amps and your espresso of course
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
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 ;-)
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.
Hier finden sie die wichtigsten Informationen zum Matching unserer Röhren.
Wir bieten zwei unterschiedliche Matchings an. Diese unterscheiden sich wie folgt:
1. Unser Premium Matching:
Hierbei wird der Ruhestrom der Röhren punktgenau gematcht und auch die Steilheit (Transconductance) der Röhre gemessen.
2. Das sogenannte Standard Matching:
Die Röhren werden nur nach Ruhestrom selektiert, der maximale Unterschied darf max. 2,9mA betragen, eine Messung der Steilheit findet hier nicht statt.
Standard Matching, welche Optionen und Kriterien bietet das Standard Matching?
Das TAD Standard Matching beinhaltet ähnliche Qualitätsprüfungen wie beim TAD Premium Matching.
Die Röhren werden aber nur nach Ruhestrom selektiert, der maximale Unterschied darf max. 2,9mA betragen, eine Messung der Steilheit findet hier nicht statt.
Während der Ruhestromprüfung findet auch das Abhören auf Störgeräusche mit Klopftest statt.
Verhält sich die Röhre stabil und laufruhig, so wird entsprechend den Meßwerten, die TAD Grade Nummer ermittelt und direkt während der Prüfung etikettiert.
Diese Grade-Nummer kommt auch auf die Verpackung, so dass das Grading sowohl anhand der Röhrenschachtel als auch auf der Röhre selbst nachvollziehbar bleibt.
Matching- und Symmetrieoptionen für Vorstufenröhren
Paarweises Matching für Vorstufenröhren bedeutet, dass zwei geprüfte Röhren in einer realen Audioschaltung (Kathoden-Bias) die gleiche Verstärkung in jeder einzelnen Triode aufweisen, also vier charakteristisch identische Systeme.
Das Matching in Paare beinhaltet unsere Symmetrie- bzw. Balance-Selection (max. 10% Toleranz). Wir empfehlen das Paar-Matching für HiFi-Anlagen sowie bei allen Stereo-Anwendungen.
