Need to recap my Classe Audio DR-8 Amps - need suggestions

Caps that need reformed are garbage and should be replaced.

This is not correct, I’ve done it many times with new old stock Siemens that have been on the shelf for 15 years or so, and other good quality ones, and I’m sure the ones in the Classe aren’t rubbish probably Nichicons.
So long as it’s done as I stated above it works great, that (10v-20v) is the volts you increase every hour or so.

garebear since you know some much why don't you reach out to Classe' and see how far that gets you.  The OP asked about sending them back to Classe' for repair and it is relevant and correct that the company doesn't exist anymore other than as a name brand as part of a holding company.  On another forum two reviewers with long term relationships with Classe' reached out on behalf of someone like the OP and it got them nowhere. But you go ahead and try yourself.  Make sure you have your facts straight before you call me or anyone else out. 

Classé audio is now owned by the parent company. Sound United. (   soundunited.com. )  they own Denon,Polk,Marantz,Def-Tec,Heos,Boston Acoustics and now Classé.  Maybe contact them and see what they say. I imagine at the least you could find a authorized service center to do the work.  Good luck. I love Classé. I have a CP-800 and 3X  CA-M600’s. Absolutely love them.  

The DR-9 was the last effort of David Reich at the old Classe. I assume the DR-8 is in the same strata. If so, they are very fine amps and - if in need of aid - I think that they're worth the effort.  As for the "new" company, I've not found them particularly helpful nor responsive.
