Ortofon T-20

Moving-Coil Transformer

Ortofon T-20


The T-20 transformer has been engineered on the same principle as the T-30 so it offers a high performance level.

Designed essentially for use with Ortofon moving coil cartridges, which have an internal impedance of 3 ohm per channel, it can also be used with cartridges of different manufacture in the 2 to 4 ohm range.

The T-20 includes a bypass position for switching between moving coil and magnetic cartridges.
