Hpims, thanks for colaborating my point with your experience with the 240.
Electrolytics deteriorate and must be replaced periodicaly. If the 225 starts to hum tomorrow do you think it was perfect today. NO, the sound degrades slowly and at some point the cap will deteriorate to the point that you can hear some hum, but the sound has been degrading long before you hear a hum.
