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?

Just sent an e mail to Kal at ARC. I own a Ref 5 SE pre and Ref 150 amp. Both amps have white Teflon caps. His answer may be relevant to the OP's Qs.

1200 for a few caps and some wire that you have to solder your self seems steep to me. How many caps are they giving you, what is the value and what are they made of? This is something they should sell you a cost. Seems like they are making a profit off the back of a defect.
