The only difference is that 1 is a polyester 100v whereas 4 and 11 are ceramics 50v. Unfortunately nowhere on the five sheets sent to me by the vendor is there an issue or date reference. Still, with the components I had to hand, it now works, if out of spec. Thanks to all who took the trouble to send information, it is much appreciated. 73, Brian At 14:47 12/03/01 -0000, you wrote: >Well, my manual shows it in the parts list as 1uF 50V but since the >highest voltage in the RA1792 anywhere is 28V, and only 15V on the RF >AMP then I would have thought 25V would do. > >However, the circuit diagram shows it as 0.1uF.
