I did this for you Jim. Is there any upgrades for this amp? There is for the DH-500. Do you know what year yours was made Jim? Is there an address on the back? I have gotten 2 dates when Rockford Fosgate bought Hafler. I have looked every where. One said they bought them in 1977. Then another says 1987. I have not a clue. I looked for manuals and upgrades. I found a thread about a pro board which is different than the DH. I also found a reference to the power caps.
