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.

Veerapaneni, how can you tell if the amp has old or new capacitors? I have a fairly new ARC 250 so wondering what capacitors I have.

Probably a dumb question but is the upgrade kit free? Similar to a recall if Teflon caps are defective ...

The old Teflon capacitors are white ones and the new ones are gold color and small size. The kit for both Amps is around 1200-1300 as I my warranty expired.

1200-1300 is reasonable. How do they sound compare to originals? Did ARC perform the fix?
