Triad high reliability audio transformers provide the durability and precision required in today’s
demanding designs. These transformers are available for a wide variety of applications. The line
of Red Spec audio transformers is designed and constructed to meet the rigid requirements of
MIL-T-27E. These transformers feature an epoxy molded case, gold plated leads and exceptional
operation from 300 Hz to 100 kHz.
