Here is one used Mitsubishi mono/stereo power amplifier model DA-A10DC tested and working, I got this from a living estate sale two years ago and was found in good condition, it is around 100 watts per channel, chassis and face plate is in good cosmetic condition. Sold as is or as described, please pay with pal or credit or debit card. I ship in the USA only. I ship fast and insure and put a tracking number on it.
