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 D400 mk2 Caps
Hello,
Anyone know where to get the 4 big can Caps?
67,000 mfd 75 volts I think. I cant tell size though.
Audio Research does not repair this amp anymore.
George Meyer could not find them either.
I could replace them in my own time but can't find them.
The amp is running fine but I want them replaced.
The volts measure ok but if left off for.more than a week or so it may zap after charging up.
Protect mode blinks for a second
But stays on ok and sounds Grest.
Thanks George.
