[M3talhead] takes us through a very informative repair of an old tube radio. In this case, his radio was from the late 30s. He was able to find the original data fromRadiomuseum.org. He painstakingly dismantles the radio components and the cabinet. Instead of completely modernizing the internals, he replaces the bad parts and brings it back to functionality. He wanted to do an MP3 upgrade, but rather than wire directly into the radio, he built an AM transmitter for his mp3 player.
