ayre v-5xe has consistant noise after warm up


My Ayre v-5xe amp makes a sound for a split second everytime after starting the amp. The sound comes from the amp at around 9 minutes after turning on and listening. It sounds like a smoke detector only not nearly as loud. The noise is noticable, but that's it, almost mechanical in nature. Has anyone dealt with this before. Michael at Ayre had no advise but to send it back, and even then there may not be a fix.

Could it be a tube in your SF pre amp going microphonic?
Perhaps you can borrow a substitute preamp to confirm .
Also try a decent pair of shielded XLR interconnects .
