Links to the websites of a number of antique radio repair services are included in this list. I have no specific knowledge of any of them, however.
The old table radios are a lot of fun. Some sound pretty good. Many have excellent reception.
I have This Airking model probably from the 1940s sometime, sitting on top of a bookshelf for display only at home. I have not fired it up for years knowing it needs some work, but I clearly recall as a kid many hours spent listening and twiddling with it. Am and shortwave reception was phenomenal, with an internal antenna only. I tried many a similar later model transistor shortwave radio over the years working at radio shack, and nothing ever came close. Its a project for me someday to try and get this guy running again on my own that I very much look forward to.
