John, the procedure for that is on page 3-1 and 2 of the manual, but it 
may not be necessary.  Lots has been published about these and I'm sure 
a Google search will turn them up, in particular there's an Italian 
authored pdf from, I think, a member of this group.  There are some 
electrolytic caps that will need to be checked and replaced where necessary.

Having said that mine came back to life after being in dusty storage for 
about ten years and all it needed was a good clean...
