Overview of the 845BSE Tube
The 845 is a legendary, directly heated triode originally introduced in the 1930s for radio transmission and high-power audio. It is highly prized by audiophiles for its immense, muscular scale of sound, deep bass, and high linearity. [1]
The "BSE" suffix denotes a specialized version of the standard 845 tube:
  • "B" Variant: Typically represents a high-grade mechanical structure or unique aesthetics (often a signature blue-tinted glass or specific carbon/graphite anode coatings to dissipate heat efficiently). [1]
  • "SE" (Single-Ended): Identifies optimization for Single-Ended Triode (SET) amplifier designs, which operate purely in Class A to maintain maximum warmth and tone purity. [1, 2]
Common Applications
You will find JINVINA 845BSE tubes serving as the primary output power valves in massive, reference-grade integrated or monoblock tube amplifiers: [1]
  • Amplifier Pairings: Commonly used alongside 300B or 6SN7 tubes (where the 300B acts as a driver and the 845BSE acts as the final muscle amplifier). [1]
  • Power Capacity: A typical 845 Single-Ended setup yields anywhere from 16W to 40W per channel depending on plate voltage voltages (which can reach up to 1250V). High-power push-pull variants can step this up to 100W. [1, 2, 3]
