Akai AA-500 amplifier

Solid State Stereo Pre-Main Amplifier

Outstanding Features:

Silicon power transistors for the final stage obtainable highest performance and temperature characteristics.

"E.P.C." (Elactronics Protection Circuit), protecting the power transistors from damage in case of short circuit at the output terminals.

Completely O.T.L. system, distortion-free, well damped reproduction.

110 W music power

Direct reproduction from the tape head by equalizer for head.

Independent filters for high and low also tone controls for right and left respectively.

Low power consumption and instant functioning by "All transistor system".

Little heat radiation

Headphone and DIN jack
