就现代的音响而言,人们对胆机的音色动荡、醇厚、甜美和充满“大厅效应”的音质久久不能遗忘。尤其在数码音源(CD、VCD、DVD等)一统天下的今天,音响烧友们将胆机与数码音源进行组合,真正的改善了数码味,产生了珠联璧合的效果。可是,胆机体积大、耗电多和价格昂贵,而半导体场效应管,则体积小、耗电低、噪音小,最难能可贵的是,它的工作特性与胆管雷同,稳定度极高,缺点是耐力差、速度快、工作电源电压比胆管低(胆管的工作电源电压为200V～300V,场管一般只有几十伏),但两者的工作
In terms of modern sound, people have a long and unforgettable sound of turbulence, mellow, sweet and full of “hall effect.” Especially in the digital audio source (CD, VCD, DVD, etc.) dominated the world today, the audio enthusiasts will be combined with digital audio amplifier, the real improvement of the digital taste, resulting in a perfect match effect. However, the large tube amplifier, power and more expensive, and semiconductor FET, the small size, low power consumption, low noise, the most commendable is that its working characteristics and bile duct similar to the high stability, shortcomings Is poor endurance, speed, low working voltage than the bile duct (bile duct working voltage 200V ~ 300V, field tube generally only a few dozen volts), but the work of both
