Abstract

Recently I noticed an irresistible offer on Craigslist: a Majestic 3C70 AM/shortwave radio for just US $50. This model dates from the 1930s, when such radios came in gorgeous wooden cabinets. The specimen I stumbled on was still in the possession of the original owner, who used to listen to it with her family when she was a little girl. The wood and speaker fabric were nicely preserved, probably looking much as they did when Japan attacked Pearl Harbor. I snatched it up.

昏暗的灯泡，聪明的想法：这个DIY测试设备是修理老式电子产品的必备工具

最近我注意到Craigslist网站上有一个诱人的报价：一台Majestic 3C70 AM/短波收音机只要50美元。这款收音机可以追溯到20世纪30年代，当时这种收音机装在华丽的木柜里。我偶然发现的这个标本现在仍在原主人的手中，她小时候经常和家人一起听这首歌。木材和扬声器的织物保存得很好，可能看起来很像日本袭击珍珠港时的样子。我把它抢了起来。
