Headphone amplifiers


The AMP-02 amplifier is a continuation of the AMP-01. It is an extension of the AMP-01 design with a modified PCB.
The device is equipped with an additional gramophone stage for MC inserts. On the bottom there is a multi-step fit selector for MC (10 Ohm – 100 Ohm).
The AMP-02 is designed to listen to high quality headphones with a 6.3 mm stereo jack plug. It was equipped with a delayed headphone system.
The housing of the amplifier was made of a solid body of high quality aluminum.
AMP-02 amplifier power is provided by a specially designed external power supply for AC 16V AC. A separate 230V power switch is installed in the power supply unit.
The unit can work as a MM / MC phono preamplifier for integrated tube or transistor amplifiers. The output can be output from the headphone output jack via the Jack Stereo / RCA Stereo jack.
Warning. The device requires careful selection of signal wiring.
The power supply is designed for the AMP Series Amplifier. It is an optional feature for AMP-01 amplifier, but for AMP-02 it is necessary.
Its appearance is related to AMP amplifiers. It is made of a solid body of high quality aluminum. A specially designed toroidal transformer was used.
