I got my mics back today, and everything seems to be working correctly. I will say that I am not happy with the service that I received. I spent nearly $400 to replace the damaged parts in two of my akg451 pres. When I got the mics back the first time, they were working, but one of them had inverted phase. I have not done any work on the mics myself, and the only person that has been inside of them was Richard. At first he did not believe there was an issue even with all of the images that were sent and he was adamant that this was not done at his shop. I asked him to take another look, and he did. He switched a couple of the wires in the xlr connection and wanted to charge me another $97 + shipping. I balked at having to pay anything and he gave me a, "Whatever Jeff" and ended the call.
Bottom line is mics are working properly, and he ended up doing the right thing in the end.
If anyone has any contact info for someone who can work on AKGs please let us know.
