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.

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