The only doorknob caps that are stable enough for use in tuned circuits 
have either N750 or NPØ temperature coefficients.  Doorknob caps that 
are designed for coupling and bypassing service have higher temperature 
coefficients, and are therefore not satisfactory for use as tank 
circuit padders.
