Which tubes fit Line Magnetic amplifiers and where can you get them?

With Line Magnetic, the range extends from classic 300B and 845 concepts to powerful 805 single-ended amplifiers. Typical examples are the LM-845 Premium with 845, 300B, 310A and 12AX7, as well as the LM-805IA as a pure 805 Class A amplifier. This makes Line Magnetic a brand where often not just one single tube, but a complete combination of driver and power tubes is important. Many suitable types for these device families are available from BTB in selected quality, on request also as matched pairs for the power stage.
