This is a step-up transformer for moving coil cartridges using Tamura Corporation's transformer TKS-83.

The case is a custom-made product made by a sheet metal manufacturer.

This product is wired for MC cartridges such as DENON DL-103. By changing the wiring, it can be used for low output cartridges such as Ortofon SPU.

Tamura's quality assurance record including frequency characteristics of this transformer is attached. Tamura is a manufacturer that also makes transformers for onboard satellite equipment, so there is no doubt about their high level of technology and reliability.
