NRG Control Amp

Hi, I came accross one of these the other day, and I have not been able to find any information on these amps. I am hopeing someone can lead me to a review or if anyone has any experiance with them I would like to hear what you think about them.
made in michigan...early early nineties. incredibly good....its possible that the folks at cerious technologies can give you more to go on...they made unity back in the day, and demoed with nrg.
Call me at (423) 227-2185 and I can give you the name and number of a person who can probably repair your NRG amp. He was the co-designer of the NRG amp.
Correction on my phone number (423) 227-2158
