Ebay has some AM transistor radio kits, i.e., unbuilt
http://ebay.to/1UiPPFA

as well as a variety of tube radios (AM, AM-FM. & AM-FM-SW), all built

and some AM tube kits http://ebay.to/1UiOXAN

one of which - a 7 tube AM radio - for $9 features:

two in the discharge standard circuit;
Modulated at 465KHz
Plastic shell for the new material, and never go back to feeding.
Each test port circuit Ic levels.
Schematics, assembly drawings, and the other parts list, technical
documents are complete.

Despite the description, it uses transistors, not tubes.

Probably something lost in the translation. Just as in England instead
of tubes they would be called valves.

Could be the instructions are also in Chineese.
