Don't know; as I mentioned above, I purchased it used.
I not so concerned about it after talking to a few people including the owner 
of the store where it was originally purchased and someone at Adcom.
Both a friend with a good amount of electronics knowledge and the fellow at 
Adcom both think that the clicking I hear during normal listening is caused 
by RF from the switching on or off of electrical equipment (doorbells, etc.).
