When traveling in another city I stumbled across an old Yamaha solid state amp which had several small speakers in it, maybe they were 3 inches each. The grill cloth was the same as the G-100 series...kind of coppery brown with horizontal dotted lines running across it. I was in a big rush and didn't write the name or number down and now I am curious about that amp. The reason is that I found a YouTube video of a Vox Night train played through a 3" speaker and it sounded rather interesting. The break up was tremendous and the speaker coupled with the Vox was safe as it was rated at 30w. Anyone have any idea what it was, that amp?
