This is a D & A Hornet Amplifier in excellent condition other than the fact the BTL receive boost does not work. I can't find the schematics nowhere online so I am working in the blind. I am selling it as is. At 2 watts in it dead keys about 60 watts out and swings to about 150. I have replaced all of the electrolytic capacitors in it and it will be good for many more years.
