  • Patented multi-ribbon filament / cathode provide four emissive surfaces per filament, equating to 32 electrical cathodes (eight filaments x four surfaces = 32). This unique design provides far greater bass impact and fast dynamics.

  • Extreme dark plates insures high gain and maximum signal transfer.

  • All glass is hand blown and formed at the KR Audio factory from ultra durable SIMAX®, a world renowned borosilicate hard glass, creating a durable anti-resonant protective shell.

  • The polished metal bases of the 845 tubes provide excellent heat dissipation. Anti-resonant compounds are added to dissipate vibrations, reducing microphonics.

  • The white Ceramic bases of the power tubes handle extreme temperatures with ease, and anti-resonant compounds are added to dissipate vibrations, reducing microphonics and increasing clarity.

  • Gold plated pins provide an optimal surface and interface to any quality tube socket.

  • Each power tube is internally serialized, and 24kt gold leaf identifies each tube as a genuine KR Audio product.

  • Each power tube, from start to finish, requires an average of 12.8 hours of labor to construct.

  • The craftsmen at KR Audio have been building tubes for over 30 years.
