The Story Of Circuit Master

Back in the mid 70’s CB radio was all the craze, for me it wasn’t just a hobby it was an obsession! Always on a quest to improve the quality of my radio’s distinct clear clean sound. Soon my passion for CB was getting noticed and people started bringing their radio equipment for me to duplicate that big clear sound, it didn’t take long and business really blossomed.
