I've been working on a mic preamp for a little over a month now. It consists of a NE5532 differential input stage, followed by a BC547 emitter follower output stage. I'm still working out all the bugs though. I am fairly new to Electrical Engineering. So, all feedback is very welcome. I have breadboarded the whole thing, but I have yet to apply voltage. I want confirmation that everything looks ok before I do so I don't blow anything up. I have provided two emitter follower output stages, but, I am leaning towards the top/first one. Simply because the voltage divider step was needed for the op amp as it set up in a single supply confirmation. So, using the existing divider in my circuit would be beneficial.
Here is my schematic, and all parts values are provided as well. I also am having issues of what to exactly do with the 2nd amp in the NE5532. I for now have the output of the 2nd amp feeding the inverting input, and the non-inverting input being feed by a voltage divider (9v) the divider then connects to pin 4 of the op amp itself.

Any feedback would be great, and again thank you guys so much for all the help you have already provided. I'm learning tons and I feel I'm getting better at implementing ideas and design techniques.
