Hey all, I sold some P-700 power amps from a Marantz 1150d to someone who needed them for a Marantz 1150 as I understood the 1150, 1150d, and 2275 had the same basic power amps. His unit has 6 pins on the P-700 and the ones I sent only have 5 pins. Looking at the schematics I have for both units, it shows 6 pins on both. I am guessing Marantz made a change and the SM's I have are post-change. Is there a way to make these work? In the SM picture, I only see 3 wires on the 6 pin plug and the 1150d unit I removed them from has 4 wires on the 5 pin plug. Three wires go to the filter cap and one goes to the relay board. Any help would be much appreciated and might save a Marantz 1150 that is blown. Thanks, Rich
