Question from Mr. R. S. I apologize for being too hasty in my request for assistance, since I am awaiting some silver-mica caps which are as closely rated to the originals as possible. If there any members who have replaced them, it would be helpful to know how critical the values should be to maintain the 487kHz for the ZF.
I have calculate the SABA Circuit from the Superhet 455W Unit
The 455W has variable Coils on all Circuits, therefor the Cv= "Padder" (440pF) is fixed, the recommendet Value is: nominal Value +/- 1% to 2,5%. Hans M. Knoll
