一台富丽VIP—3000HCMK—Ⅱ放像机在使用过程中因发电机输出电压升至300V而烧毁电源变压器,在找不到原配件的情况下,笔者用电视机变压器代换后,效果良好,下面就其代换方法作几点说明: 第一,原机电源电路见图1所示,虚线框内为代换后新加的元件。第二,代换变压器选用31～35cm(12～14英寸)黑白电视机通用电源变压器,次级输出电压在17～20V
A magnificent VIP-3000HCMK-Ⅱ player in the course of the use of the generator output voltage rose to 300V and burn the power transformer, can not find the original accessories, I use the TV transformer substitution, the effect is good, the following The substitution method for several points: First, the original machine power supply circuit shown in Figure 1, the dashed box for the replacement after the new components. Second, alternative transformers use 31 ~ 35cm (12 ~ 14 inches) black and white TV universal power transformers, the secondary output voltage of 17 ~ 20V
