Does anybody have any suggestions as to where is the best place to take the audio signal from if I want to display audio input level on a LED VU meter?

mdainsd said:Shot,
The MPS3640 data sheet I looked at has "negative values" listed. Its a PNP switching transistor, which is what is called for. What I do see for both types is that the pinout (when looking at it with the flat facing you is) from left to right e,b,c.. Be sure to double check before installing. The pinouts on the board are c,b,e for that transistor. Abe used the square pad at each transistor site for the collector (or maybe more correctly "pin 1" as the majority of the transistors used have the collector on pin 1), and I added those to my schematic..
