Yamaha - AX-390 - Integrerad halvledarförstärkare

This is a pre-main 2X60 W amplifie with Phono and direct CD terminals, The volume uses an electric volume, remotely controlled.
It is equipped with tone control and continuous loudness. Delivered in mint state with it's original user manual and remote control.

The amplifier will be securely packed and shipped through Catawiki International carrier with insurance.

Technical features:
Yamaha's original linear damping circuit has been adopted, and the internal impedance has been thoroughly reduced by using a lot of extremely thick wires, etc., so that a stable damping factor independent of the frequency change of the source can be realized.
In addition, a powerful LiD (low-impedance drivability) power supply is used for the power supply section, and a large transformer and large electrolytic capacitor provide stable drive capability even if the impedance of the speaker decreases.

A CD direct amplifier is installed to reproduce the sound of CD as it is.
In this system, a CD direct amplifier with ultra-low noise is mounted immediately after the input terminal, improving the S/N ratio by 10 db in actual use. In addition, the impedance is also reduced, making it less susceptible to external noise.

In order to eliminate the effect of vibration of the power transformer, it is floating by vibration proof mount.
