I just found 6 Mullard IEC 6922;s made in Blackburn, with codes such as B5I3. From what I gather, you can't tell the year of manufacture from this code, the second digit is the year and could be 1965 or 1975, Not gold pins. Any thoughts?
Looking for a smooth sounding 6922 variant
Hi folks. I am currently auditioning some cables and am starting to suspect that a bit of higher-frequency harshness (fatigue, just a bit) might be due to something else in my system. Could be anything, including the cables I'm auditioning. I wanted to eliminate other causes, and so I'm looking for a pair of 6922' variants to put in my VAC Signature IIse to smooth out the higher frequencies a bit. I think I've got telefunkens in there now. Can I get some recommendations? Perhaps Mullard makes a nice 6922. Please answer with direct knowledge/experience. Thanks.

@peter_s -Hi Peter. Following this thread and I found the following review on the Blackburn Mullards. "The Blackburn Mullard is fully burned in. The weakness of the tube is the anemic bass and midbass, producing an unbalanced sound spectrum. The upper mids and highs are glorious, however, detailed, harmonically layered, 3-dimensional and natural sounding -- among the best I have heard. This tube is great for a narrow range of music (in my system), but not for general use. For instance, a soundtrack of nature sounds from the forests and savannas of Africa is the most layered and natural sounding that have heard thus far. I use this recording as a test for soundstage and imaging. Another downside of the Mullard is a more restricted dynamic range compared to a Siemens 6922. I wonder if the Mitcham production fills in the bottom frequency range, offering as detailed but more balanced sound." Also, have you looked through this site. A lot of great info about 6922 and variant NOS tubes. https://www.audioasylum.com/scripts/d.pl?audio/faq/joes-tubes.html David |
