MC Stepup Transformer "ETR-800P"


I have regarded clear sound and low tone quality as important not to spoil a good point of Cartridge.
I think that stepup transformer ETR-800P acts on not only Miyajima-Lab's Cartridge but also the cartridge of other companies effectively.

- ETR-800P is installed in a beautiful TEAK case.
- The calking material is "paraffin"
- Highest grade core material, permalloy 80 for the core of the transformer is used.
- There is a changeover switch of Low,High,Pass.
- The left button is a demagnetization function.

The DEMAGNETIZER switch removes the magnetization of a cartridge and the stepup transformer.
Please push this button for ten seconds while listening to LP music. While you push the button, the music stops.
A cartridge and a transformer are demagnetized by the interchange signal of the LP.
A sound is slightly cleared by demagnetizing it. Please use demagnetization every several months.
Because this demagnetization method does not add electricity, the cartridge is safe.
