I believe that when this preamp was sold it had a Lifetime warrantee.I know that my DR4 did and that was around'90. You may not be the orig. owner and they probably would use that to weasel out of the deal.

Yes, I think it is probably not a blown input amp transitor but more likely a bad solder joint. I've got the function generator, the oscilloscope and the soldering iron. Also have years experience in Aerospace design engineering. I can probably poke around and find the problem.
I'm surprised at Classe's policy of "no information" for the owners of the products. Most audio products I've owned have come with, at the very least, a schematic and often a parts list as well.
Anyhow, if some of you Classe DR-6 owners out there have had this problem and know the circuit weak spots, let me know.
Your sage advice is appreciated.
