I got my DA-80 from E-bay I paid $354 in non working order
after replaceing a few blown transistors on the left pre-driver board amd seting the bias the amp has now been in service for over two years now, clean pure class A sound
yes, the amp gets hot as hell put there is a plus to this,the output transistors not only does the positive part of the in coming singal but does the negative also so the transistors are always on, on a clas AB amp one transistor does the positive and one does the negative so the transistor are on only half the time, at the point where the one transistor comes on and the outher turns off is were you can get whats called crossover distortion on a class A amp this is no problum becouse the transistors are linear and thats were you get the heat.
