Onkyo M-588F Stereo Power Amplifier - Huge Meters WOW - 200WPC


These are becoming harder and harder to find in good working and cosmetic condition. They typically have scratched tops, broken VU power meters, and dents.

This example is the complete opposite. It's not only in overall very good condition, but it's also working just like it should as our shop testing revealed.

Also you know you're looking at something special when there's a dedicated page on the always relevant and classic HiFi website The Vintage Knob. According to them, this was the last of Onkyo's high-end 2-channel audio development.

To ensure a happy life in its new home, we calibrated the meters and biased the transistor; which yielded a super clean and impressive 200W.
