<< Ed,
 
 I'm not sure what Eimac says.  I've been running the 4-125A,
 and the 4-250A that way for years with no problems.  But I guess
 a problem could occur someday.  I don't run the coils that often
 though.  Maybe someone will check Eimac's (CPI's) website.
 
 Cheers,
 John

is needed and how yo urun them?What kinda things should I know about them and
