本机电路结构较简,适合业余制作,可用于磁带放音和转录磁带。不失真输出功率2×3W。前置放大用双前置IC,BA328。R_1、R_2C_1和R_3C_2分别组成低频和高频端频率补偿。W_1、W_2是放音电位器,录音时则用于控制录音信号电平。本机采用交流抹音和交流偏磁,偏磁源是一个新颖的
The circuit structure is simple, suitable for amateur production, can be used for tape playback and transcription tape. No distortion output power 2 × 3W. Preamplifier with dual front IC, BA328. R_1, R_2C_1 and R_3C_2 respectively constitute the low-frequency and high-frequency end frequency compensation. W_1, W_2 is the playback potentiometer, recording is used to control the recording signal level. The machine uses AC wiping and AC bias, bias magnetic source is a novel
