Originally designed for the output stages of audio frequency amplifiers

Delivers up to 17W while remaining compact

Similar to an EL34 with a lower output power

When overdriven, EL84 power tubes contribute to a distinctive chiming and articulate sound when compared to 6L6 tubes

Each tube is meticulously measured for all critical parameters of performance including transconductance, gain, noise, and microphonics

Tubes are selected by hand, rigorously tested, subjected to an extended burn-in period for stability, and remeasured before final packing

Q: 1. What version of Windows does the USB-recording feature require? Can I attach it to my Win 7-32bit PC?

A: This interface comes with a free version of Tracktion recording software which will run on Windows 7 with a minimum Intel Core 2 Duo 2 GHz Processor, 5400 RPM Hard Drive, and 4 GB RAM (8GB recommended).

Q: 2. Would the tube work in a Rode NTK? And is this tube manufactured in Germany?

A: This twin- triode tube is made in the Slovak Republic, and is also known as the 6922, which can be used as replacement valve for the Rode NTK microphone.

Telefunken has been in the high end audio tube business for many many years. I just believe this is the best preamp tube available. The tube i had pulled out was supposedly a selected Chinese 12AX7. Although I do not have the measuring equipment to measure any differences, I am completely satisfied with the ECC83.

Q: 8. would this be a good replacement for the tube inside my akg perception 820 mic?

Q: 9. is this a cordless microphone?

A: The Telefunken M80 is not a wireless mic. This is a dynamic handheld that needs to be connected via cable.

[Noval] I know these tubes have no comparison to the original Telefunken tubes. I still really like them. 5

[760 mA] Excellent product for CD player and service. I would buy more from this seller. 5

[0.035 lb] I purchased these tubes to replace the stock tubes in an ART Pro MPA II, and they are exceptionally smooth, turning a chevrolet into a mercesdes basically. The unit now sounds like a 4 figure higher end pre amp. 5

[Noval] Amazing sound, Excellent... 5

Thomas	08/08/2024
[760 mA] I am using the Telefunken ECC83-TK/12AX7 in the v1 position in my bass preamp. It has a smooth bottom and mid-range without being too bright and harsh at the higher frequencies. Sounds nice with my 4003 Rickenbacker. 5

Jeff L	02/07/2024
[Noval] I have a Rode K2 for vocals and the stock electro-harmonix tube is a little bit too sharp in the highs, but this new production TF 6922 sounds great after having some burn-in time. After just 8 hours or so it sounds great, 20+ hours it sounds awesome. Not quite the same warmth as some NOS tubes that I've used, but excellent clarity and smoother top end, and importantly, super low noise. Especially at this price, it's a great choice for the K2 and I'm sure it would sound great in the NTK as well. 5

Shaun	23/05/2024
[760 mA] I popped this in my ART preamp and it sounds amazing. I really love how warm this sounds 5

Joseph	05/05/2024
[6.3 V] I used these tubes as replacements in my TL Audio PA-2 Preamp/DI and the difference in sound was huge. More defined and musical. So far used for drum overheads with KM184s and Bass DI and I was very happy with the results. I was surprised there was such a noticeable difference. 5

Samuel	17/04/2024
[Noval] telefunken ecc 83 brought out the best sound from this marshall dsl5c. low noise and cleanest sound i ever had from this amp. huge difference in the tone quality after I swaped in the tele funkens. though its a bit pricey compared to other brands, I beleiv its well worth the money if you are into precision quality tone from your amp 5

[0.5 oz / 14.2 g] If you have an audio system that is capable of displaying the difference, these are much above the $19 version of this tube. I have a Magnum Dynalab MD809t internet tuner that features a 4-tube push-pull output which came equipped with the lesser-costing version of this tube; after replacing them with the Black Diamond series I hear a distinct difference in audio quality. It's nice to get back to the warmth and depth of sound that distinguishes tubes from transistors. With these Black Diamonds there is no tube hiss or hint of distortion -- it's vintage wine for the ears! 5
