Pass Labs XA-25 on all the time?

I just had my Pass X150 in for service, and I spoke with Kent there about replacing power supply. He said they are just beginning to see the first Alephs coming in for cap replacement, almost 30 years old. Those are monstrous, and monstrously hot, Class A amps. 

He also said no need to worry about premature aging of caps unless large Class A and you leave it on all the time. 

So, if he's right, I guess most Aleph owners don't leave them on much, or if they do, 30 years is premature for Pass Labs caps.  

I leave my X150 on during day (space heater) and off at night, but it doesn't actually run very hot, so I could run it all the time with confidence. It's 150 into 8, 300 into 4.  First 5 watts Class A

If it is a Pure class A amp like the XA30.8 or XA25, turn in off. These amps pretty much draw full power even when no signal is applied. The heat generated with class A will shorten the life of the parts inside, mostly caps, your electric bill will be noticeably higher, and will add extra heat to the room that will be a problem during warmer months. If the amp is a class A/B, Its your call, class D leave on all the time.

I now power up my SMc Audio up one day prior to  listening every week.
