This time I introduce YAMAHA B-1；power amplifier. It was put on the market in 1974. List price is 335,000JPY. It mounts V-FET. 360Ｗ(8ohms　1khz　distortion 0.1％） Output 150Ｗ+150Ｗ（８ohms/４ohms both ｃｈ　20～20khz,　distortion0.1％）

There was a UC-1 controler with needle meter as a option unit. The list price of UC-1 is 50,000JPY. It is possible to use it as a speaker selector.

I think B-1 is very powerful. When I connected B-1 with NS-1000M. The sounds of NS-1000M tremendously changed,especially low sound.

There are kind of weakness. Speaker terminals are very small and delicate. Weight is 37kg. It's too heavy.
