The Titans of Tone: A Comparative Guide to 211, 845, 813, and 811 Vacuum Tubes
The Titans of Tone: A Comparative Guide to 211, 845, 813,...

In the world of high-fidelity audio, few components command as much reverence and mystique as large power tubes. Originally engineered for the demanding world of radio frequency (RF) transmission, tubes like the 211, 845, 813, and 811A have found a second life in the hearts of audiophiles. These "transmitting tubes" are prized for their linearity, power handling, and the unique sonic character they impart on music. They represent a departure from common audio tubes like the EL34 or KT88, operating at dangerously high voltages and requiring specialized amplifier designs.

This article delves into these four iconic tubes, comparing their origins, technical specifications, and sonic signatures. We will explore the classic rivalry between the 211 and 845 triodes, and contrast them with the rugged, high-power 813 beam tetrode and the high-gain 811A triode.

진공관 선택

전자관을 선택할 때는 먼저 특정 응용 회로의 특성과 요구 사항에 따라 적절한 관 유형을 결정해야 합니다. 둘째, 선택한 튜브의 매개변수가 애플리케이션 회로의 요구사항을 충족하는지 확인해야 하며, 특히 한계 매개변수가 충분한 여유를 가져야 합니다.
