Amplifier Problem - Revised Schematic
In the interest of clarification, I have added some information to the
schematic of the tape deck headphone amp that I'm having problems with. Some circuit paths are now labeled: http://i240.photobucket.com/albums/f...mplifier-1.jpg As always, the points at which voltage readings are marked with a star are NOT producing the voltage indicated. The +7V location is measuring 131mV instead. The other two points where a star is indicated are measuring between 20mV and 30mV (fluctuating slightly). I am starting to think that a circuit OUTSIDE of this circuit might be at fault, because NOTHING inside of this circuit seems to be faulty...but the darn thing still WILL NOT work. |
