Description

Up for sale is a classic piece of Japanese hi-fi history: the Trio KA-8100 integrated stereo amplifier.
Note on the Brand: Trio is simply the original Japanese domestic market name for Kenwood. This amplifier was built in the same Japanese factory with the exact same layout, circuit design, and premium components as the legendary Kenwood KA-8100 sold internationally.

This unit has been fully serviced and recapped, ensuring it performs at peak factory standards with complete reliability for years to come.

Why This KA-8100 Stands Out
Trio = Kenwood Heritage: Trio and Kenwood are 100% identical in engineering and build quality. You are getting authentic Kenwood performance in a rare domestic Japanese edition.

Fully Serviced & Recapped: Aged electrolytic capacitors have been replaced with fresh, high-quality audio-grade components. Switches and potentiometers have been cleaned and lubricated for quiet operation, and bias/DC offset have been checked and calibrated to original specifications.

True Vintage Power: Rated conservatively at 75 continuous Watts per channel into 8 Ohms. These vintage watts offer immense current headroom and drive demanding speakers with authority.

DC Amplifier Topology: Features a direct-coupled circuit layout for exceptional phase linearity, tight bass extension, and a clean, detailed soundstage.

Exceptional Phono Stage: Built-in low-noise phono preamplifier, making it an ideal centerpiece for vinyl lovers.

Built Like a Tank: Solid brushed aluminum front panel, machined metal knobs, and smooth tactile switches.

Technical Highlights
Power Output: 75W + 75W RMS (8 Ohms, 20Hz to 20kHz)
Brand/Model: Trio KA-8100 (Identical to Kenwood KA-8100)
Design: Direct-Coupled (DC) Integrated Amplifier
Inputs: Phono, Aux, Tuner, Tape 1 & Tape 2

Preamplifier Options: Pre-out / Main-in loop for flexible system integration

Tone Controls: Bass and Treble with selectable turnover frequencies + Subsonic filter

Condition & Performance
Sonic Condition: Pristine working order. Thanks to the recap, it delivers a whisper-quiet background, deep punchy bass, and crystal-clear highs without the dynamic compression or hum of aging original caps.

Cosmetic Condition: Very well-preserved faceplate and knobs with classic vintage character.
Controls: All switches and knobs operate smoothly without crackle or static.
