我在少年时代就喜欢摆弄收音机,当时为他人修理或组装收音机是一件令我感到愉快的事,在我住宅附近可算得上一个出名的“无线电少年”了。最初我对音响产生兴趣始于立体声初期时代,唱片由78转的 SP 转向 LP 密纹唱片,但是 LP 唱片实在太贵,不是吾辈少年所能企望的。因此信号源选择了广播,当然不是现在的 FM 广播,而是无线电杂志上介绍的超外差式 AM 收音机。 I used to play the radio in my teenage years. It was a pleasant thing for me to fix or assemble the radio for someone else, and I could be called a “radio teenager” near my home. Initially I was interested in sound began in the early stereo era, the LP 78 LP record LP LP records, but the LP record is too expensive, not what our young people can hope. So the source chose the radio, of course, not the current FM radio, but introduced in the radio magazine super-heterodyne AM radio.
