Audio Research D400 mk2 Caps

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.

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.

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.

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

Both screw terminals but size may be different.
