Line LM211IA integrated tube amplifier audio at home
The 211 was originally designed in the early '20s, deriving its heritage from an earlier tube used during WWI in Navy radio transmitters. If you compare the plate characteristics of DHTs, such as the 2A3 or the 300B, the 211/845 family is much more linear. Of course, this linearity has a price: a high plate voltage.
211 SE1
"Overview and design considerations: The 211 and 845 transmitter tubes have always presented somewhat of an enigma as a large power tube typically run single ended and originally used in WWII to transmit radio signals across battlefields with plate voltages in excess of 1'000V to maximize linearity and gain.

The small tubes have choke supply, and separate PSU for every half of the two triodes. The schematics is the best I know of - based on the experience with tens of 845 amps I rebuilt and the GM-70 sister amp that we sell. The big tube has silicon rectified PSU. The small tubes - have very good tube rectifier. 211 has its own huge choke as well.

Latest SPONSORED VIDEO Single-ended triode amplifiers (SETs) have a considerable following, but even their most devoted fans admit that its maximum power output is not among an SET's strengths. You'd be lucky to get an SET that puts out 7Wpc, and some (like those using the 45 tube) are closer to 2Wpc.

211 e 845
Article by Hiroyasu Kondo-san, Audio Note. From Sound Practices Issue 2, Fall 1992. T he 211 creates a formidable impression because of its shape. But the 211 may appear old-fashioned and unsophisticated to high-brow maniacs for audio equipment. Perhaps this is the reason why there are only a few amplifiers that employ the 211 tube today.

Non-linearity. The tube's high current and high gain are made possible with very small distances between the electrodes - less than 1mm. The side effect is that this tube is less linear than a 211, 300B, 2A3, 845 or 805. So such an amplifier needs feedback. Ours is slight, 6dB compared to 20dB in pentode tube amps or 40dB in transistor amps.

Originally designed for radio broadcasting transmitters, the 211 has excellent linearity. This lends itself to an audio amplifier with no feedback (neither local nor global) but still low distortion. Lack of feedback made for a very musical sound. Due to its pure graphite plate, the 211 also offers a big maximum dissipation of 75 watts.
