[Boatanchors] vacuum tube radio kits

[Carl]

If you do not offer it as a kit but just a collection of parts that limits 
the liability due to some damn fool or someone looking for a big payday. 
Above all talk to a lawyer. Since its not a kit the FCC isnt involved 
either. Have someone else handle the transformer shipping for you if you 
really want to play careful, just dont leave any paper trails.

You can also cut costs by purchasing an existing product and duplicating the 
metal work. DX-20, Adventurer, Knight, etc.A controlled carrier modulator is 
1-2 tubes and a few small components...its almost free.

Personally I dont believe there is any real vacuum tube QRP market but there 
will be with enough power to actually work someone with a compromise 
antenna. AND at 30-40W it will be sufficient to get a 10-13dB boost from a 
GG glass tube amp. It only takes around 25W to get the 1500W PEP legal limit 
on AM from a pair of 3-500/4-400's.

Get all the free marketing you can, write an article for ER Magazine and 
provide a web page link in your many forums signature.
