Tisha is >absolutely right<, removing the rotating turret from an SP-600 
has almost zero room for error.  Add to that, replacing the capacitors 
has zero room for error.  You'll be doing something like.... 27 or so 
total.  You can't do 5, put the turret back, reconnect the 455 KC IF 
wires on the side, test your work and keep repeating till the caps are 
done.  Every time you remove the turret, the chances of something 
breaking increase by an order of magnitude.  Break off one of the 
"fingers," the entire band is done.

The capacitor replacements must be accomplished in a single, proper 
removal of the turrett.   You'll want to use all 1KV ceramic disc 
capacitors in the turrett.  As I recall, they are all .01ufd.
