现代名机前级放大器大都设有精确的电源稳压电路,高手焊制土炮时更将电源稳压部分视为重点。发烧友现用的电子管放大器,如果在B_+电源中加入稳压电路,放音效果将得到明显改善。这是因为,稳压电路除了使B_+电压稳定,不受供电电压波动和机内电流变动的影响,还具有很好的滤波效果,使B_+输出电压的纹波极低,所以一台胆机如果电源变压器有足够的容量,为提高音效应加装稳压电路。
Most of the famous aircraft pre-amplifier with precise power supply voltage regulator circuit, master welding gun more when the power regulator part of the focus. Enthusiasm tube amplifier, if the B_ + power supply in the regulator circuit, the playback will be significantly improved. This is because, in addition to stabilizing the voltage regulator circuit B_ + voltage stability, free from supply voltage fluctuations and current changes in the machine, but also has a good filtering effect, so that B_ + output voltage ripple very low, so a gall bladder Machine if the power transformer has enough capacity, in order to improve the sound effect should be installed regulator circuit.
