EAR Yoshino V12
在V12，添加帕拉维奇尼的最新心血结晶，是在阀放大器设计一个全新的概念。忘了其他更传统的设计 - 在V12的设计思路是一个完全的“一张白纸”。
输出阀是间接加热EL84/6BQ5 pentodes，6每通道。平行推拉“A”级电路的特点，五极管模式。该电路提供了极好的线性度和极低的失真。此外，V12采用帕拉维奇尼高度发达的平衡桥接模式，定制超宽带输出变压器，并没有总体的反馈。
关键设计目标为V12分别延伸在频谱的两端的频率响应，改善低级别的细节，并提供完善的扬声器耦合。所有已成功地实现，以及来自低价五极管输出阀极好的可靠性。该放大器是完全稳定到任何负载，并且将提供可靠的服务。

该电路是不是V12的唯一独特的功能;该个案也是独一无二的。蒂姆想要一个更自然，和谐的面貌，以他的新的放大器，比东西粘在空中传统设计与他们的接触，工业看着变压器，硬角，和阀门较少攻击性。筋膜是圆形，在一个半月型，具有定位在相对的机箱顶部的两侧的左，右声道的阀门。在V12的完成是示范性的，采用木的阀盖，镀铬筋膜和镀金控制旋钮。
这个名字V12的设计灵感来自于经典的捷豹V12引擎Tim的激情。蒂姆决定用6 EL84的每个通道在新的电路。
比较在世界上最好的汽车发动机是有效的，这个放大器是如此的非常流畅和成熟。很少有，得到的V12远离作为阀放大器。它的开放性，速度性和权威性都无法比拟的。视听的信。
该放大器是每通道50瓦，有5个线路输入，并且可以从4到16欧姆连接到任何扬声器负载。它是完全稳定到任何负载，并且将提供可靠的服务。

The V12, the latest brainchild of Tim de Paravicini, is a completely new concept in valve amplifier design. Forget other more conventional designs - the V12 is a totally "clean sheet of paper" design.
The output valves are indirectly heated EL84/6BQ5 pentodes, 6 per channel. The parallel push-pull class "A" circuit features Pentode Mode. This circuit provides superb linearity and very low distortion. In addition, the V12 uses Tim de Paravicini's highly developed Balanced Bridge Mode, a custom ultra-wide bandwidth output transformer, and no overall feedback.
The key design goals for the V12 were to extend frequency response at both ends of the spectrum, improve low-level detail, and provide perfect loudspeaker coupling. All have been successfully achieved, along with superb reliability from the low-priced Pentode output valves. The amplifier is perfectly stable into any load, and will offer years of reliable service.
The circuit is not the V12's only unique feature; the casework is also unique. Tim wanted a more natural, harmonious look to his new amplifier, something less aggressive than traditional designs with their exposed, industrial looking transformers, hard angles, and valves sticking up in the air. The fascia is rounded, in a half-moon shape, with the left and right channel valves positioned on opposing sides of the top of the chassis. The V12's finish is exemplary, with wood-capped valve covers, chrome fascia, and gold-plated control knobs.
The name V12 was inspired by Tim's passion for the classic Jaguar V12 engine. Tim decided to use 6 EL84's per channel in the new circuit.
Comparisons to the best motor car engine in the world are valid, for this amplifier is so very smooth and sophisticated. There is very little to give the V12 away as a valve amplifier. Its openness, speed and authority are beyond comparison. Seeing and hearing is believing.
The amplifier is 50 watts per channel, has 5 line inputs, and can be connected to any loudspeaker load from 4 to 16 ohms. It is perfectly stable into any load, and will offer years of reliable service.
