I haven't had the personal experience, but when you see old class A Krells for sale, (as one example) the seller will frequently mention that all of the power supply caps have been replaced at factory; and I have read that it's because of the high heat generated over years of constant use. For that reason, I have always avoided buying a used one even though I was tempted when I saw one that hadn't been refurbed.
Is there no truth to this?
