I just finished a 650B and found that the rf tracking can be improved on the broadcast band by cheating the dial scale alignment somewhat. With the tuning gang plates fully meshed, try setting the dial scale to the first line to the right of the end of scale line. Now re-align and check your rf tracking. If it is better, but not perfect, move the dial scale a little more in the same direction and try again. I found this procedure helps somewhat.
