Its funny, I needed a 10db gain amplifier that used a 2n2222 and being lazy and not wanting to MATH i typed into google 2n2222 10db preamplifier and low and behold,  it came up with an answer that was what i actually wanted. Sorry to the OM i stole this from, i will edit this later with a link back to your site.

So anyway, I simulated in LT Spice and it was spot on, -6db input and +4db output, thats 10db and just what the doctor ordered. Who needs math when google can elmer like the best of them.
