How will I know when a Krell KSA-80b needs to be recapped?

The hotter an amp runs the faster the caps will deteriorate. If you have owned it since new you can guess how many hours are on it. If not things like heat-sinks turning from black to purple or even lighter would show lots of hot hours. A tech can look at the ripple on the caps and see approximately what shape they are in. Personally I would not like caps leaking in my classic Krell ever. I would have it looked at if you are unsure of condition.

I had this done on my KSA 80B in 2018 at the Krell Factory.  The did recap the PS with the big caps, and also several caps on each board, and set the unit up to drive one ohm Apogee Scintillas.  Been running fine ever since--3 years now.

What were the adjustements made to the amp in setting up to drive the 1 ohm Scintilla?
Thanks
