Hey guys, I have a question and need some help. I have a Channel Plus MDS-6A amplifier that runs my home stereo system. A couple boards fried in the unit and I can't find replacement parts or even a used MDS-6A at a reasonable price and the units are all but discontinued. A company called Nortech has taken over Linear and their customer service isn't worth a crap. Any suggestions or help would be greatly appreciated. Thanks in advance. JC
