Provided it's all working, I'd say you'll be very happy and have an awesome sounding amp!
I'd get an amp tech to check it over - I did this with my 5150-II head when I bought it second hand, as I wanted to be sure it was all okay. I got the tubes changed at this stage too, wasn't too confident about that as it was my first tube amp, and at least this way I knew what was in it.
Enjoy the new amp!
