Cyrus 2 Stereo Integrated Amplifier Hifi Engine Refurbished Serviced Unit Made in England
MM MC with pre-main amp with Mission Cyrus  (circa 1987)
The Integrated Amplifier designed based on the same idea as Cyrus1.
In addition to the increased output, Cyrus2 has improved current supply capability.
It also has an MC input designed with emphasis on noise and hysteresis elements.
The power transistor is equivalent to the military standard.
This power transistor is specially manufactured for Cyrus Electronics and is an ultra-fast, linear device
In addition, the transistors in the driver stage are manufactured by a factory that supplies British semiconductors for
military use.
This series is cheap because the nonmagnetic, nonconductive metal substitute resin does not match the Japanese
culture and the appearance is almost nothing.
Checked, maintained, adjusted.
There are paint peeling, scratches and  dirt
