• E88CC / 6922 JJ preamp tube.
• Also interchangeable with 6DJ8.
• Low micro-phonics & reliable.
• Warm tone.
• Made in Slovakia.

These are excellent musical sounding tubes. They're quieter than some of the alternatives (such as the Sylvania) but with a well defined midrange. If you're upgrading your stock tubes you should definitely hear a good increase in sound quality. A relatively new release (for a tube!) they've been well received so far. Can be used in a range of audio devices.
