Back to the original question/post at hand.
My old 70's Sansui 8080 would get hot when cranked for quite a while so I put a muffin fan on it. It certainly helped and everyone noticed the sound didn't flatten out any longer. Sounded good cold though.
My Krell FPB amp does like to be played a bit to get the components warmed up, or so I figure. Like I said years ago, I feed the fish, cook dinner and clean up a bit whilst it plays. After that all is well. And yes, this is the same amp stuck at Krell in CT while they re-organize after the owners passing. The KCT pre-amp is always on, or so it seems, as it stays very warm to the touch. I feel the on/off switch is there for decoration.
asvjerry: I am getting up there myself. One of the prime things that keep me moving forward and smiling is to remember I have a lot of living to do yet so I better keep going. Even with CIDP I enjoy & relish the day. I hope it helps you get a better outlook. Maybe a Happy Birthday from someone you don't know will help a bit.. All the best, John
