1、V20为综合放大器V20为综合放大器 The V20 is a completely new concept in valve amplifier design. 该V20为是一个完全新的概念,在阀放大器设计。 Forget all other more conventional designs, the V20 is a totally “clean sheet of paper” design. 忘记所有其他更传统的外观设计, V20为的是一个完全干净张纸设计。 The output valves are the indirectly heated ECC83 twin triode ty

2、pe, 10 per channel, operated in a parallel push pull class “A” circuit featuring Enhanced Triode Mode, as used in both the EAR 859 Single-Ended Triode Amplifier, and the EAR 861 push-pull triode amplifier. 输出阀门是间接加热ecc83双三极管类型中, 10 的渠道,经营一个平行推拉阶层 , 电路具有增强三极管模式中,由于所用的两个耳朵859单端三极管放大器,以及耳朵861推-拉三极管放大器。

3、 This circuit provides superb linearity and very low distortion. 这条赛道提供了极好的线性度和极低的失真。 In addition, the V20 uses Tims highly developed Balanced Bridge Mode ultra-wide-bandwidth output transformer, and no overall feedback. 此外, V20为用途添的高度发达的均衡桥模式超宽带宽输出变压器,并没有一个整体的反馈。 The key design parameters were to e

4、xtend frequency response at both ends of the spectrum, improve low level detail, and provide optimum loudspeaker coupling. 主要设计参数,以扩展频率响应,在两端的频谱,改善低层次细节,并提供最佳的扬声器耦合。 All of these points have been successfully achieved in the V20, with superb reliability from the low priced triode output valves. 所有这些

5、要点已成功地实现了在V20为,以高超的可靠性,从低价位三极管输出阀门。 (All valves in the V20 are true triode valves.) (所有阀门在V20为内容是否属实三极管阀) 。 The circuit is not the only new thing with this amplifier, the case work is new and unique. 该电路是不是唯一的新事物与这放大器,因此案件工作,是新的和独特的。 Tim wanted a more natural, harmonious look to his new amplifier, s

6、omething less aggressive than traditional designs with exposed industrial looking iron transformer cores, hard angles, and valves stuck up in the air. 添希望看到一个更具有天然的,和谐的期待他的新放大器,东西少侵略性比传统的外观设计与暴露工业展望铁变压器铁心,硬角度,和阀门卡在空中。 The fascia is rounded, in a kind of half moon shape, with left & right channel val

7、ves positioned on opposing sides of the amplifier. 该筋膜是整数,在一个种半月形,左与右声道阀门定位于对立双方的放大器。 Finish is exemplary, with wood-capped valve covers, heavy chrome-on-brass fascia, and gold plated control knobs. 结束语是示范性的,木材私自阀盖,重铬对黄铜筋膜,以及镀金控制旋钮。 The name V20 was inspired by Tims passion for the motor car, and in

8、 particular, the famous V12 Jaguar engine. 名称V20为灵感所添的热情,为汽车,尤其是著名的V12引擎美洲虎发动机。 The original prototype had twelve output valves, and we at Yoshino could not resist calling it a V12 amplifier engine! 原样机已产出12个阀门,而我们在吉野无法抗拒称它是V12引擎放大器引擎! Tim decided to uprate the project when the true potential of thi

9、s new circuit became apparent, and it crystallised as the present V20 specification, with no less than twenty output valves. 添决定uprate项目时,真正的潜力,这个新的赛道变得明显,它的晶体状,因为目前的V20为规范,没有一个不少于22输出阀门。 Comparisons to the best motor car engine in the world are very valid, for this amplifier is so very smooth & sop

10、histicated. 比较,以最好的汽车引擎,在世界上是非常有效的,因为这是放大器,所以非常顺利精密。 There is very little to give this amplifier away as a valve amplifier: openness, speed & authority are three good words to describe it. 有很少给这个放大器以外,作为一个阀放大器:开放性,高速管理局三好个字来形容它。 The amplifier offers 20 watts per channel, has 5 line inputs, and can b

11、e connected to any loudspeaker load from 4 to 16 ohms. 该放大器提供20瓦特每通道,有5个线路输入,可以连接到任何扬声器负载,从4至16欧姆。 It is perfectly stable into any load, and will offer years of reliable service. 这是完全可以稳定到任何负荷,并会提供多年可靠的服务。 Magazine Review 杂志审查 SPECIFICATIONS 规格 I.M.D. 管理学院 less than 0.5% 小于0.5 Output Damping Factor

12、输出阻尼因子 10 10个 Signal to Noise Ratio 信号信噪比 93dB (Less than 0.4mv) 93分贝(小于0.4mv ) Input Sensitivity 输入灵敏度 40OmV 40omv Input Impedance 输入阻抗 47kOhms 47kohms Power Consumption 功率消耗 150 V/A 150的V / 1 Weight 重量 22kg 22公斤 Size 大小 42cm(W) x 44cm(D) x 13.5cm(H) 规格必须(宽) x 44厘米(深) x 13.5厘米(八) Valve List 阀门名单 26

13、pc ECC83 (12AX7) 4 pc ECCS2 (12AU7) 26pc ecc83 ( 12ax7 ) 4电脑eccs2 ( 12au7 ) Power Output 输出功率 20 watts per channel 20Hz to 20kHz 20瓦特每通道20Hz至电池 Power Bandwidth 功率带宽 12Hk-80kHz -3dB (Half power) 12hk - 80khz技术指标- 3dB (半功率) V20 V20为 Yoshino V20 吉野V20为 Leave it to Tim de Paravicini to come up with some

14、thing so deliciously twisted that no tube crazy can resist it.它留待添德paravicini要拿出东西,所以deliciously扭曲了,没有管的疯狂无法抗衡的。 The new EAR/Yoshino V20 integrated amplifier, despite costing a not-unreasonable-by- todays-standards, 2495, looks like nothing else and sports a quantity of tubes rivaled by few.新穗/吉野V20

15、为综合放大器,尽管耗资不收不合理的,按现在的标准, 2495年,看起来好像什么都没有了,体育相当数量的管击败由寥寥可数。 Hell, the only items I can think of off-hand with similar numerical appeal - i.e., more tubes than any sane person would deem necessary - are high-enders like the GRAAF GM200 OTL with its 16 output tubes per channel, and the recent Silvawe

16、ld design with 48 per monoblock.地狱,唯一项目,我认为在场外,一方面与同类数值呼吁-即,更管比任何理智的人会认为有必要的-是一种高层次的诱惑一样gr aafgm 200ot l其1 6个输出管每通道,以及最近si lvaweld设计百分之四十八单块。 Now the V20 isnt quite up in that league in tube count, but neither is it in price.现在V20为是不太在该联盟中筒计数,但两者都不是,它在价格。 Better still, its profusion of glassware is of the common-as-muck variety, so heres a rare chance to have a plethora of
