Ok, I need some imput. My fathers Harman/Kardon Citation 16 was no longer working. I called Harman/Kardon and they sent me to this repair shop in Chicago. They said that one of the transformers was shot and he basically riged the amp to run off of one transformer. Now we found out that the Phase Linear 4000 preamp has some major problems, and I am going to send it to Circle Stereo in texas to get it refurbished. I found that place online.
My question is did I get ripped off with the amp? He did not refurbish it, and I don't like the idea of running off of one transformer. But at the time I thought that was the only option, because that is who Harmon/Kardon sent me too. And if I did, does any one know where I should send the amp to get completly refurbished?
