Story & Notes
The Technics SU-V6 represents an era of Japanese hi-fi engineering focused on performance, reliability and solid construction.
This example has undergone extensive electronic and mechanical restoration, going well beyond a conventional capacitor replacement.
Particular attention was given to the ageing switches, contact assemblies and signal paths — common sources of problems in vintage equipment.
Following restoration, the amplifier demonstrates outstanding measured performance, with extremely low distortion and closely matched channels.

Bench Test Summary
Test equipment: QuantAsylum QA403
Load: 8 Ω, both channels
Test frequency: 1 kHz
THD+N @ 1 W: 0.0122% L / 0.0129% R
THD+N @ 10 W: 0.0051% L / 0.0050% R
THD+N @ 40 W: 0.00294% L / 0.00281% R
THD @ 40 W: 0.00029% L / 0.00072% R
Frequency response: Essentially flat from 20 Hz to 20 kHz.
Channel matching: Approximately 0.2 dB.
Tested output: 39.0 W L / 40.6 W R at the highest documented test level (not a maximum-power measurement).
All values are actual bench measurements obtained after restoration.
