Tube amplifiers respond differently from transistor amplifiers when signal levels approach and reach the point of clipping. Free shipping. Its triode mode softens the tone for vocals and strings, while the ultra-linear setting is ideal for punchier, dynamic music styles. If you're really looking for the best, you'll be hard-pressed to do better than the Luxman, but be prepared to shell out quite a bit of dough. This, combined with the spread of TV, produced a 'golden age' in valve (tube) development and also in the development of the design of valve amplifier circuits. The problem is that the amplifiers need to be extremely linear, otherwise "intermodulation distortion" (IMD) will result in "crosstalk" between the multiplexed channels. The Dared and the Gemtune BL-02 are interesting options, as they combine old-school valve technology with modern features like Bluetooth, for the best of both worlds. The introduction of the Williamson amplifier in 1947, which was extremely advanced in many respects including very successful use of NFB, was a turning point in audio power amplifier design, operating a push-pull output circuit in class AB1 to give performance surpassing its contemporaries.

Its class A circuitry ensures a clean and consistent output with minimal harmonic distortion, and a signal-to-noise ratio of over 85 decibels. Obwohl diese Bewertungen immer wieder verfälscht sein können, geben sie ganz allgemein eine gute Orientierung. The advantage of this is that a single valve "repeater" amplifier can amplify many calls at once, this being very cost effective. If you're among them, you're in luck, because there are countless tube-driven amps available, and they look and sound better than ever. With its stainless steel chassis and analog meter, the Yaqin MC-13S (around $706) is as aesthetically appealing as it is sonically impressive. Some tubes were capable of being driven so hard that the anode itself would glow cherry red; the anodes were machined from solid material (rather than fabricated from thin sheet) to withstand heat without distorting. In power amplifiers built using vacuum tubes, as discussed later, generally the load consists of an output transformer, which adapts the impedance of the speaker to the load required by the vacuum tube. The open loop linearity of valves, especially triodes, makes it possible to use little or no negative feedback in circuits whilst retaining acceptable or even excellent distortion performance (especially for small-signal circuits). The antenna or following circuit stage typically contains one or more adjustable capacitive or inductive component allowing the resonance of the stage to be accurately matched with carrier frequency in use, to optimize power transfer from and loading on the valve, a so-called "tuned circuit". Vacuum tube amplifiers have been around for a long time, and many enthusiasts claim they provide a warmer, fuller profile than solid-state devices. There is no valve analog of the complementary devices widely used in "totem pole" output stages of silicon circuits.
