VAC Phi 300.1 won't power on.

Upon plugging in my VAC Phi 300.1 power amplifier I heard a soft pop and then it went completely dead.  This was after I had removed and cleaned each of the  8 output tubes.  I've contacted VAC but as it's the start of the weekend I wonder if any VAC users have encountered a similar situation.  I live in Alaska so sending it back is a massive ordeal.  


One thread I read mentioned the "Sentry Circuit" which shuts down the amp if a tube goes bad to avoid damaging the amp.  Is anyone familiar with this circuit, and how to reset it? 

Take a look inside the amp. A soft "pop" could be a shorted coupling cap. Look for a cap with white stuff coming out one end.
