Has anyone here had issues with their c100 and ground hum?

I got one off ebay for a good price but it has a nasty ground hum issue. I tested another condenser mic with the same cables / preamps and even tried with a battery operated preamp, the zoom h6. Ironically with the h6 it sounded the worst -- not only was it ground hum but there seemed to be some higher frequency harmonics with the ground hum that were not present on the wall powered preamps.

Im planning to send it in to sony for service but was wondering if anybody had experienced anything?
