is hard on the power supply caps. That is, once charged, allowing the unit to sit for extended periods is harder on it than regular routine use.

I can only relate one example of this. I had an Eico tubed integrated amp that I used a bit, then stuck in a closet where it sat for several years. I brought it back out and the second time I turned it on it popped loudly after 10 minutes or so. Scared the bejeebers out of me.

This was repeated several times, the last time before a tech friend of mine who immediately said it sounded like one of the PS cans arcing between sections. Having no way to determine which cap, I replaced all four as they were not expensive. That cured the popping.

The tech said that these big caps lasted longer when properly "exercised."
