CORAL AX-3000
88,000 yen(around the 1965 time)

Description
@
AM/FM multi-stereo synthesis amplifier which attained high sensitivity-ization.

FM stereo monophonic automatic change function is carried.

All silicon transistor composition is adopted.

The power transistor is protected with new E-P-C equipment (New Electronics Portection Circuit and all the electronic formula guards).

A tape head can use it direct.
