Genesis 350 Servo Power Amp does not work Please Help

Hi ! I got a Genesis 350 power amplifier and it does not work. All is fine but the steering chip is damaged (software) . Looking for software so i can program a chip i find or a complete original chip. Please help!

Please write if You have an idea let me know! I read that Genesis was sold to a company from Boulder Colorado and then sold again. Maybe You got the address to the firm that owned  Genesis when 350 was introduced? Regards Christopher
