Audio Research D400 mk2 Caps

Hello George , found second hand at Ebay , brand Cornell Dubilier , seller nri-industrial , North America.

but also new at the company Cornell Dublier , you should only know if they fit in your poweramp 

Good luck 

You can also check Nippon Chemicon KMH series, and Frolyt (Germany) EBH-NV.

Both screw terminals but size may be different.

I would also ask ARC, just in case, to provide me with data of the capacitors used back then or any other information.

But i assume that anything made now days would be superior.

Audio Research gear is a pain to work on, everything is tight. What is the lead spacing between the cap terminal screws? How tall is the cap? You don't have to use exactly 67kuF.

Bumping this because Pyramid Audio serviced my "unserviceable" D400mkii.

Issue is those original caps are direct soldered to the board, which makes it a PITA to work on.

The tech at Pyramid Audio in Austin found a solution. He should have records of what he used if you give them a call. I know a bunch of his peers warned him off working on the amp, but he did it anyway and I'm happy because this amp sounds fantastic.
