I'm the original owner of my first generation (non-balanced) Lexicon MC-12 Cinema Processor. I've heard and read that the power supply in these units often fail and need replacement. I just got off the phone with a rep from Lexicon. He discounted my concerns, stating that (in general) he know's of no vulnerabilities with the power supplies in these units. That's fine, and it was good to hear. OTOH my unit is about 10 years old and I think it's safe to say, considering this thing is essentially "On" 24/7 - the power supply will eventually need to be replaced. I've been inside the unit to upgrade it. Never had a problem with it. I'm sure I would be able to replace the PS with no problem. The Lexicon rep. would not give me any information about the PS (part#, etc). There is an authorized service center in my area, and the Lex. rep. instructed me to contact them if my unit was ever in need of service. I've also heard that the PS in the MC-12 is not a proprietary Lexicon part and a replacement can be purchased from various electronics supply dealers. I have no idea if this information is accurate. Does anyone have any specific information on a replacement PS, and if so - where I can pick one up? I guess I could call the service center and try to convince them to acquire the part and sell it to me. May be wishful thinking ... thanks. -paul.
