[Heathkit] SB-200 Question

I wasn't watching the EMail  addy and this didn't go to the right place, 
so here goes again.

This raises a more "generic" question that I have been meaning to ask 
the Elmers/Engineers/Wizards that hang out here.  Is there a rule of 
thumb in making  these parasitic chokes, or are they specific for each 
tube and/or circuit?  Can I use Carl's circuit with 3 turns of wire in a 
home-brew linear and be assured that I am reasonably close?
