Tungsram ECC83 / 12AX7 / B339
Made in Hungary from around 1970-80s. Have the metal stamped clip, copper grid posts, support rods. This tube is very open, fuller sounding, moderately warm and very transparent usually with very low noise and microphonics. Sonically comparable only to top NOS contenders as Mullard, RCA etc. Standing out with their dynamics, solid bass and great overtones lately became very sought after by guitar people. Great for hi-fi and guitar! We believe that this is an excellent ECC83/12AX7 NOS tube with the best quality/price ratio of today. We currently have Military OEM tubes available.
Quantity in Stock: 16 pcs
Price: €70.00/each; €145.00/matched pair
Per your recommendation, I purchased this tube as my phase inverter position. It is now my go-to tube for that spot! Just a nice, strong tube that lends its fat tone to my amp in a wonderful way. If I ever get over the RCA long blackplate's glorious tone in my V1 spot, I may try the 'spare' Tungsram there just to see if what I think.
ReplyDeleteThanks, Koray!
This tube is my favorite in V1 position, superb definition and clarity, every detail is present. Thanks Koray to all your help in my DIY amp project.Your a great dealer and your knowledge about tube and electronic is impressionant.

I've had these tubes (military specs white boxes) for a few days in my system now and they sound wonderful. Detailed, and neutral with great bottom and highs. a great value indeed.
ReplyDeleteThank you Koray for your recommandation and great service.

Koray recommended 4 matched Tungsram 12AX7s for my very demanding phono stage and they have been the best of many NOS and new tubes I have tried - they have superb clarity, coherence and musicality, and most importantly they are dead silent. Thanks for your excellent recommendation and wonderful service. Simon, Melbourne/Australia.
ReplyDeleteAbsolutely fantastic is all I can say about the tubes I got a few weeks ago. I replaced all 8 tubes in my vintage Conrad-Johnson PV-5 pre-amp with: 5751 GE Black Plate Triple Mica; 12AX7 Milspec Tungsram; and 5965 Telefunken tubes. I am 100% vinyl and now hear everything that is in the grooves of the albums, and I haven’t heard that in years. On both my classical and jazz albums, the detail of the instruments is unbelievable. The overall sound is what I would describe as warm or natural – no harshness at all, just a beautiful dynamic range and soundstage, which from my correspondence with Koray, is primarily due to the GE Black Plates. It’s like you are in the concert hall or jazz club. If you love audio, this is the ONLY place to buy your tubes. Thank you Koray.
ReplyDelete“Skip from Tampa, Florida”.
I got the military spec Tungsram 12ax7 with a recommendation from Koray to gain more bass and mids and it did that exactly, great tubes. I strongly recommend this site as they have quality tubes and best customer service.
ReplyDeleteFollowing Koray' suggestion I bought this tubes in boundle with the Tungsol 12Au7 to replace the whole preamp section of my Primaluna Prologue2.
ReplyDeleteThe improvement vs the original set is terrific expecially at the hi end frequencies. More microdetails, brighter voices but with a warm touch, stronger perception of notes' elapsing time, deeper and more controlled bass, Even the soundstage benefits of a more stable image and above all a sensation of a more precise & faster sound.
Following another Koray' suggestion I already ordered the Tungsram sister 12AU7 to go beyond the TungSol+Tungsram performances ... Let you know soon ...
A special mention about Koaray' customer centricity attitude ... one of the 12au7 gonna accidentally broken after 1day ... I'm going to receive a replacement free of charge !!!
A great lesson for all the skepticals about on line buy and non EU/US sellers.

ReplyDeleteTungsram ECC83 for flatwounds.
Sylvania Gold Brand 5751 for roundwounds.
Awesome sounding tube at an awesome price! Sounds BIG and open in V1 and PI slots in my Dr Z amp. HUGE improvement over the stock tubes! May I added that the shipment was quick and very well packaged. Thanks Koray
ReplyDeleteI bought Tungsram 12Ax7 and 12AU7 combo after reading a tip for the
ReplyDeletePrimaluna amp owners. Now, i can tell you that is true for the Rogue Cronus Magnum too. The sounsstage is really 3D and well focussed.
Now i am looking for preamp tubes.I am waithing your suggestions Koray....thanks.

Koray recommended this tube to me, and I must say I was really impressed. Sounds to my ears very similar to a Mullard ECC83. The best thing about this tube is it is really quiet. I actually found that this tube works great in the Phase Inverter position of my amp, where it definitely warmed the sound up, and gave it more of a 3D quality. As always service was amazing, and the tubes got here fast. Thanks!
ReplyDeleteMerhaba,
ReplyDeleteKoray Bey'in tavsiyesi üzerine bu lambayı Presonus Bluetube DP V2 mikrofon preampimde kullandım. Cihazın kendi üzerindeki lamba Çin malıdır ve bu lambayla yanyana getirdiğinizde bile kalite farkını kolayca görebilirsiniz. Asıl sese olan etkisinden bahsetmek gerekir hiç şüphesiz ki... Bu lambayla birlikte "giriş seviyesi"ndeki preamp adeta şahlanarak sınıf atlamıştır. Low noise, wide headroom ve warm etkisi üzerindeki stock lambaya kıyaslanamayacak kalitededir. Bir üst seviyedeki preampe para vermek yerine mevcut preampiniz eğer lambalıysa mutlaka Koray Bey'le görüşmenizi tavsiye ederim. Eminim ki size sunacağı çözüm mutlu olmanızı sağlayacaktır.
Tecrübesi ve bilgisinin yanısıra güvenilirliğiyle de ayrıcalıklı olduğunu kanıtlayan Koray Bey'e teşekkür ederim.
Saygılarımla,
Burak Kaynarca
great tube ! after reading the tip about this tube for primaluna, i've ordered a quad matched for my dialogue 6 monoblocks. Combined to tungsram ECC82 from this shop, it has reached my amps in another league compared to stock tubes. Details, low noise, soundstage is more holographic.
ReplyDeletevery good service quality.
thank you and hope to deal with koray again.
Finally,I bought Tungsram 12AX7 and 12AU7 to replace new Tungsol 12AX7 and Genalex 12AU7 after Koray's famous suggestion in here.
ReplyDeleteI can say that after all these replacements my PrimaLuna Prologue 2 has ultra clean and extended high frequencies.In fact,details are pouring to my listening room gently.
In the mean time,tubes present me very warm sound.
I felt little reduction at bass according to my previous new tubes.
Sound stage is incredible open and wide without loosing dynamics .
Thank you Koray for your recommendation and service during shopping process.
I will continue to discover nos tube world with you!
Best Regards
Tolga Kardes
I have bought 4 Tungsram ECC83's from Koray. These are just fantastic tubes for guitar. Very even toned with rich harmonic content. I'm running them as V1 in Mesa's, Bad Cats and Marshalls

My favorite AX7. Huge, muscular bass and low mids and a magical top end air. Huge imaging and wide, open sound stage. Excellent detail, clarity and dynamics. Quick and responsive. Coupled with my Sylvania JHS 5814 GP or RCA 5814 BP my system sounds incredible (naturally a bit on the bright side mind you.) I have a matched pair branded as Haltron. World class AX7!

The Tungsgrams 12AX7's are great! They are very very quiet, have tight bass with very smooth mid-range and highs. The sound stage is wide and 3D. This is one of the best upgrade I have ever done. Sounds like I upgraded the preamp...
