Hi Gregory,
Welcome to the MOTM world! As far as your gain, something is indeed
out of whack, since you should have more gain than that on the output.
Did you check resistors with a multimeter? Sometimes it's easy to
misread a color band.
As far as cabinets, I've written a little treatise on the subject:
