 eBay user: hockeywoolf - Hi Gregg, I finished the complete restoration of my Sansui AU-717 last night, and I am listening to the amp now.  I gotta tell you I am blown away!  I don't ever remember it sounding anywhere near as good as it does now.  It's completely insane.  I'm hearing things I have never heard before.  Thanks for all of your help, and for answering all of my (usually pretty dumb) questions.  I am one seriously happy camper.  Rob

       ---------- QUICK TEST ------------

      Here's a quick test I want anyone with a marginal Sansui power-protector to try.  When I say marginal....I'm referring to power-protectors that require longer than 10 seconds to latch the speaker protection relay, or the protector light keeps blinking. 

      1)  Leave your amp in a cold place overnight.  A cold garage, car...anywhere cold.  Now try to get your amp's power-protector to latch.  It will take a lot longer, if it even latches at all. 

      2)  Conversely, put your amp in a very warm place for several hours.  A hot sunny window, trunk of a car...anywhere warm.  Now many of those marginal amps will latch much faster.

      As components age, they drift away from their specified values.  This process causes otherwise perfect working electronics to act-up.   This test changed your amp's component values temporarily, hopefully demonstrating the affects of component aging.
