Tom-
I don't recall any particular problems nor tricks involved in that model; it's pretty straight forward. Of course the tar blocks must be emptied and all of the paper/electrolytic caps replaced. While you are replacing the caps It's a good idea to check the resistance of all resistors above 10K- they are very often way too high.
The most irritating and difficult problem will be dirty and weak switch contacts in the RF stage.
Alignment isn't difficult but you do want to make sure that your sig gen is accurate by using a freq counter.
