Audio Research Reference 250 capacitor issue

One of my reference 250amp fuse blown and found that the capacitor is bad and audio research has upgrade kit to replace Teflon capacitors with latest ones. The also have new wiring in the upgrade kit. Has anyone experienced this ? I see they discontinued Teflon capacitors a year or two back.

Just got a free recap on my Ref Phono 2SE. I upgraded from Phono 2 to Phono 2SE, but after some hundreds of hours break-in the white teflon caps sounded dull and liveless.

"Dull and liveless" compared to the sound just after the upgrade, when the phono played wonderfull. After a long break-in it never reached this level again.
Of course I first changed the tubes (both steering tubes and the power tube), but with no result. So probably one or more caps did broke down. After recap (white teflon again) the Phono 2SE worked fine again.
