Used, Carver Amplifier set. The preamp has gold rca. The Main 1 out needs a new cap on one side. The Main 2 out is what I have been using. Its been like that since I got it. I have not noticed any other issues. Be careful with the gold rca. The power amp lights work. The Sonic Holography sound is really cool, and also the spectral tilt and separate left and right bass and treble, Contour and Stereo Blend. You can also plug in 2 external processors. I don’t have enough room to set up the big speakers any more or else I would keep the set. It is in storage now for a while and not being used. It is a great amp to power the JBL CF150 325W speaker set I have. It is really loud and nice sound. The speakers are not included.
