F-300 pioneer

I gave the pioneer amplifier.
but the Pioneer F-300 amplifier that does not look anywhere.
Do you know this amplifier?
It would not buy another perfect amp so 30 years ago. It's not like an auction.
The sound quality is with the sound of old. And there are very thick bass from the midrange area.
The audio system has been in my room at the last.It's fun!
