Description Technical Specs
Brand New MINT NOS Telefunken Diamond Bottom 6211  tubes. Made in West Germany. Tubes are without labels and were destined for OEM use. We have cleaned the the slight tarnish on the pins due to storage conditions.

6211 is a computer grade tube and close to 12AU7, but NOT exactly. Amplification factor is 27 to 31 vs. 18 to 19 for 12AU7. Click  6211 data  and 12AU7 data for comparison.  These tubes have a brace or flange that runs the entire length of the plates.

Consult your manufacturer if it is OK to sub your 12AU7 with 6211. Here are some comments by one of our regular customers (your results may vary): "They have wonderful golden mids....just wonderful. I would highly recommend them for someone who loves jazz or vocals.  The Tele (6211)  bass is excellent.  The 3D-Soundstage impression is outstanding.........really something. Those are some of the best tubes I have heard in the 12AU7 type, and I have tried a lot of the best NOS names."

NOT recommended for systems that are already bright or edgy. Telefunken 6211 are very bright and suitable for systems that are laid back. We do not guarantee that these would suit your taste. All sales are final and there are no return or exchanges on these. Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester.

Matched Pair is $120. E-mail us directly if you need Single or Odd number of tubes.

3 of 5 Telefunken 6211 September 7, 2007
Reviewer: Sherlock from WA USA  
We auditioned this 6211 tube together with Tele ECC802S and Tele ECC82 smooth plates. The system used Cary tube amps, and also the Cary 303-300 tubed CDP, where we compared these tubes. The 6211 has a large and impressive soundstage-bigger and more forward than the standard ECC82. The high end is more aggressive, and on systems that already are detailed and bright, I would not recommend this tube. If you have a system that is rolled-off at the high end and needs detail and sparkle, than this tube will give it to you, along with a huge soundstage. Great tube to adjust for system deficiencies.
