In 1993, JoLida designed a series of large transformers for an industrial customer in which one of the main design criteria was low noise characteristics over a wide signal. It was then suggested that if the size of the transformers were reduced, they would be highly applicable to tube amplifier transformer. Please note that in a tube amplifier, the transformer is the heart of the unit. The market criteria was that the bulk of our line would have to retail below $1,000. We just believed that the world did not need another $4,000 amplifier.
