Default Recapping a Quad 303

Has anyone used these caps from Apex Jr to recap their Quad 303's filter caps?

If so, would you recommend them?

Date code suggests they might be from 2004 or 2007, so I wouldn't recommend them. Get something more recent, 2013 at the earliest.

The filter caps should be 100v since the rectified voltage is 94v.

80v caps would be in danger of failing.

The output caps can be 63v.

If it ain't broke, break it !! Then fix it again. It's called DIY !

This is what you'd pay in Brisbane, which seems fair price parity. You can see these are quality, long-life capacitors, not the 2,000 hour junk grade but they aren't stocked here and the price includes airfreight from UK. Local delivery should be free to a/c customers. If it fits "a treat", that saves a bit of sweat making adaptor collars too. All you need then is a dozen ring terminals to suit the 5mm screws.
