About two years ago I needed to get an Adcom pre pro repaired under the warrantee. I understand the ownership changed hands around the time of my call, so perhaps this is the "new" Adcom customer service policy. I was told since I did not buy my pre from an authorized dealer there would be no repair work done under the warrantee. After I proved my dealer was authorized, they changed their tune and told me parts were no longer available for my 3 year old unit. Then they told me that my unit was so far out of date it made no sense to repair it at all. Then they tried to sell me a new unit direct from Adcom at a substantial discount ( so they said) I stuck to my guns and worked my way up the chain of command until I finally had the unit repaired for the cost of the shipping. Bottom line......you may have to be assertive to get your unit repaired if it is a warrantee issue. An interesting side note.....the unit was completely dead when I shipped it to them. When it came back it worked well except the 5.1 outputs and the on screen display did not work at all. Good luck!
