When to recap a late nineties Krell Kav 250 A.

Greetings everyone. I have a Krell 250A which bought used in 1998 and to me it works just fine. The original owner had it for about 2 months.

I have heard that you have to recap the amp at some point, however I can not hear any degradation in sound. I did replace some fuses and failed to see if the caps are swollen or leaking. The amp has always been connected to a Tice Power Conditioner and sometimes I don't listen to it for a weeks or longer. My wife and I travel a bit and I just unplug it. Suggestions?? 

While we are at it, I have heard that Krell may be filing for Bankruptcy and may not be able to get parts or service in case it's needed. Thanks in advance and best regards. 
NOW!!.... These Class A rated amps run HOT!! Over this many years everything is fried on the inside (can you say brittle) LOL.

Hi Matt. Thanks for your reply. The amp does run hot but it has good ventilation and honestly it does not sound brittle. I must say that it sounds better after two hours of being on. A bit softer and mire liquid. It does not have the buttery or romantic sound of tubes but I would hate to waste money just because it is the thing to do. Best regards. 
The KAV series was Class AB, and not amongst Krell's most sought after models. Recapping Krell's are rumored to be expensive, make sure it's worth it.
If it is working and sounding fine, leave it alone! I have many vintage amps that are still working and have yet to have any caps fail!
