I have a bnib D7104 that doesn't have a cover/endplates. Its the bottom half of the amp. If your familiar with D7's the heatsink is on the bottom. The board is attached to it. Its the yellow board that they used to switch out the older boards that had the power supply problem. They would just take the cover off the older one and put it on this. Been tested. Good to go. Brand new. $400 shipped in U.S. Can email pics if you pm me email. Thanks
