added 7 turn : 7 turn transformer to the RF Amp

The transformer should help shunt some strays to ground.
 It cut the low end off. This should help keep the AC hum down.
Using a smaller coupling cap helped the low end more.

My use for the amp is at 2MHz - 4MHz range. Looks good.
With a 100KHz - 10MHz response like this it could be used with a short wave set.
