Bugle DC on Audio Output
« on: 12 Feb 2013, 02:06 am »
Crap. My bugle had been working just fine. I swapped out a 12v AA battery pack for a 15v and now there's no sound, but I see 14+vdc on audio out. Where should I start troubleshooting? My opamps are (2) 2134 and a LME49720 at U3.

EDIT: Never mind figured it out. Faulty battery wiring.

The answer is always the same - negative side battery was connected backwards.
