In the past we’ve mentioned how there are different schools of thought in terms of how to bring a vintage piece of hardware into the 21st century.

[Derek Traxler] clearly decided to go with the latter option on his recent conversion of 1920’s era Claratone tube radio to an Internet radio and podcast player. Not only is there little left of the original device beyond its …read more

They were bulky, like all tube radios they had to warm up, and they required a pair of hefty batteries to work.
