I built a Ripper a while back and everything was working fine. As I already have a Bugle (power supply, upgraded parts, etc.) I tried the Ripper as a phono stage for the first time today. Worked fine. I disconnected the TT and line out and reinstalled them back to the Bugle. Then I noticed that the power LED on the Ripper was no longer lit. I checked R6/11, and the +/- 10v test points and they're fine, but I'm getting 19.6 volts at the LED. Is this normal, or did I blow Q1 and/or Q2?  I'm pretty sure I didn't power the Ripper down before I disconnected the TT and line out. Jeez, I hate these 'learning opportunites'  .

The LED floats between supplies.  It should have about 3V across it (forward voltage on a blue LED).  But if blown or open, then you will get the full 20V of supply (+10V - -10V).  Perhaps it is just a broken solder joint?  Possible the LED went bad.  Although it would be the first one I've seen.

Thanks for getting back so soon. Well, mark this one down. Busted LED. Do I get a prize for being the first?   Just my luck (picture black cloud over my head, Murphy dogging my every move).
