The TONA T20/40 SUT step-up transformer, is targeted enthusiasts and intended for moving-coil type cartridges. These traditionally provide a very low signal, and are difficult to amplify without noise.

The transformer is a match for tube amplifiers, as the very high gain at 1:40 can be an advantage. Can also be used with a (tube) RIAA with a good dynamic range at high levels.
At the same time, 1:20 with a more all-round gain, is usable for most cartridges with a higher output.
Tona T 20/40 has two separate inputs with completely separate windings on the primary side.
