I cant believe I started a thread about replacing 8 volume pots, it took about 10 minutes to desolder them. QSC should be sending my replacements this week....

the transformers have a bit of hum too, mechanical hum. I unbolted them and put the top gasket on the bottom to double up and leave the bolt out. My hope is to decouple to get rid of the hum. Would a sorbothane square under the transformer help. They just sit on a shelf once my work is done. The transformers weigh 15lbs each, I'm thinking four spheres per transformer

Just ordered 16 one inch half sphere's from isolate it. I went with the 50's, middle of the road stiffness. The transformers will be sitting on 4 as stated......
