Trio KA-3300 - Vintage Integrated Amplifier
The unit is in excellent condition, fully tested and in working order. It has a few small marks around the body but hardly visible. Comes with power cable.Ā
Bass and Treble Controls:
Bass: ± 8 dB at 100 Hz
Treble: ± 8 dB at 10 kHz
Loudness Control:
6 dB at 100 Hz
4 dB at 10 kHz
Pre-Main Amplifier: Uses FET differential amplification ICL (Input Capacitor-Less) system, which eliminates the input capacitor to reduce sound quality degradation.
Equalizer Amplifier: Employs FET differential amplification in the first stage to reduce phase deviation and distortion.
Power Amplifier Section:
All stages are directly connected.
Pure complementary service OCL (Output Capacitor-Less) circuit is adopted.
The output stage features a newly developed Power Darlington Block, an acoustic element composed of four transistors and a temperature compensation circuit.
Uses a triple diffused 40W block at 35W with a margin to achieve low distortion and high thermal radiation efficiency.
