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.

In January of 1995, the first of the amplifier line was introduced at the 1995 Las Vegas Consumer Electronics Show (CES) and resulted in winning two Engineering Design and Innovation Awards from the Electronic Industrial Association in spite of a skeptical dealer audience.
