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 ...
1200-1300 is reasonable. How do they sound compare to originals? Did ARC perform the fix?
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.
How many caps failed? I've own tens of thousands dollars not ARC equipment and components fails too. Shot happens.

Are your statements on the white caps based on facts from ARC? My Ref250 is months old and has a combination of white and gold caps so if white caps are known to be problematic, I doubt ARC will continue using them.

According to your system page, you bought Ref250 used with 200 hrs so you put 450 hrs in 3 years. I thought ARC warranty is not transferable and only valid for orig owner.
