Newly manufactured and cryogenically treated to resurrect the transparent tone and harmonic impact of historical Siemens and Telefunken tubes

Great for microphone preamplifiers, phono stages, and sonically tight audio input sections

Also known as the 6922, the E88CC was originally targeted for test equipment and radar, but now serves audiophiles, musicians, and audio engineers

Designed to offer precise imaging, significant dynamics, and a full-bodied soundstage

Medium gain and low noise characteristics

Dual-triode like the 12AX7 tube, but with a different pin configuration (not a direct plug-in replacement)

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 re-measured before final packing

[9] Great tube for rode k2 5

Eduardo	04/08/2024
[Noval] So far so good, made the sound warmer. 5

[365 mA] I replaced a pair of Mullards with these and the improvement in sound quality was dramatic. Better definition top to bottom as well as extended highs. A further benefit, the Telefunkens are close to broken in as delivered 5

[0.1 lb] 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

[365 mA] These are awesome tubes, if you’re looking to warm up your sound with big low end and smooth mids and highs, this is warm up galore. Very colored, great for tracking. These went on a ART PRO VLA II, and they did loads of justice. Dont forget to get a matched pair for stereo recording. Using with drums, keyboards, acoustic guitars, voice 5

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

Jack	17/06/2024
[6.3 V] Love these tubes. I replaced my Gold Lion Genalex EC882/6922 tubes with these Telefunken tubes and that added a warm tone which I really love. 5

Yun-Wen	13/06/2024
[12.5 mA/V] I bought it for my Schiit Vali 2+, I find this sound very close to Siemens E88CC where it's a very balanced tube across the range with punchy bass. Most tubes I come across are somewhat soft in their bass presentation (i.e. Tesla E88CC). This tube also has decent sound stage and separation. However the only con I would say is that this tube in general has more of a solid state kind of sound signature as oppose to tube sound. Though it could also be Schiit Vali+ own signature influence over it, I'm not too sure. But overall a very nice tube for the price, highly recommend! The other con that's not really a con is that, the box it came with has a drawing that looks a bit like a condom. I guess it's carried over from the 1970s or something like that. Just thought it's a bit hilarious. 5

[3 x 2 x 1"] I know these tubes have no comparison to the original Telefunken tubes. I still really like them. 5

[6.3 V] I put these into the input (mic/line) stage of two audio channel strips. Very nice upgrade. Really sweet extended top end and a more robust and focused bottom end. Well worth the money. 5
