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.

Agree that that repair fee is a rip for an amp that is essentially new…really ARC?
Gents, I hope I do not get a corroborating report from Kal at ARC. I would be .... extremely disappointed.
This is something they should sell you a cost.
How can ARC stay in business if sell at cost?

Seems like they are making a profit off the back of a defect.
It appears to me Veerapaneni had a cap failure and not all white caps are defective. Nothing is perfect. Since his amps are out of warranty, he has to pay for the repair.

I checked my Ref250 and it has a combination of white and gold caps. There are many reasons companies change parts and not only for SQ.
So we all thought those big fat white Teflon caps were the audio cat's meow only to discover they are kitty litter??
I don't mind paying for the parts but only hope the current ones last longer, and premium equipment worth tens of thousands of dollars should have a better warranty IMHO .
