bad sound boards scrap or resell as parts

The sound engineers I know always fix up their equipment and have good working knowledge of boards and how they work I would think if it is pro grade equipment you should do well in the parts that come off from it. I forgot the name of the plugs but their in the upper right and left corners of the mixer in the picture you provided they have three gold plated pins and I always sell them to the sound guys seems they wear out/ break down often. definitely some resale/parts value if you have the right stuff. good luck
Edit: A quick google search showed a audio recording school in PA as well as owl creek productions in west chester and patriot sound in lancaster. possible buyers and possible scrap contacts
