There is a difference in manufacturing, for sale, an amplifier that is not certified and building either a home-brew or kit amplifier. In the latter cases, you are responsible for ensuring that the finished unit meets all FCC requirements.
Dennis if that's the case then the CB Italian amps could be sold as a kit to be finished to FCC specifications. OR the FCC can outlaw every amp or kit sold, traded and given as a present without the appropriate FCC Certification paperwork. I'm curious to see how far the FCC takes this.
