DYNAKIT™ audio transformers are quality built to the exacting specifications of the original legendary design. Our output transformers, like the originals are interleaved/layer-wound and incorporate only high quality M-6 grain oriented laminations. With the exception of the Z-565 output transformer, we have retained all of the original primary and secondary windings including the same wire lead color code. Our power transformers incorporate the latest design advancements in materials, insulation, resins and construction resulting in a quieter/cooler operation. Dimensionally accurate to the original design for a trouble-free drop-in installation with a durable black epoxy finish and white logo. Dynakit transformers are made here in the USA.
