Linear power supply with large manual wound EI core transformer
Overwhelming spaciousness and expressiveness
The PT70EI is a linear transformer power supply developed for the company's Duo5 Active and Tozzi one Active loudspeakers.
Kenneth Wong's large hand-wound transformer uses TILM350 as the regulator.
If you change from a switching power supply to this power supply, your equipment will be transformed into a smooth and three-dimensional sound.
At a preview of an audio magazine, the editor-in-chief took the listening device home and still uses it ever since.
"Once you hear that sound, you can't let it go," he says happily.
It can be used for amplifiers and DACs that use switching power supplies up to 1.7A of 12V~24V, so please specify the voltage when purchasing.
*The purchased PT70EI will be shipped from the manufacturer according to the audio equipment you plan to use. If the error is in the range of 10%, there is no problem.
* The voltage cannot be adjusted for each output.
(Of the two channels, one is 12V and the other is 24V, etc.)

DC Cables Using NEGLEX OFC Conductors
We offer DC cables that use mogami's shielded wires that use NEGLEX OFC conductors to deliver pure power directly to the amplifier and DAC.
By using the two internal cores as positive and the external shield wire as GND, the coaxial structure becomes even more resistant to external noise.
