transistor subtitution
« on: March 07, 2019, 06:02:46 pm »
Hi @Jan .Is it possible to use transistor BFG97 instead of BFG135/235 in the 5w pll .Because i could not find genuine parts in my country and all fake relabeled on web ,but i have 3 pieces of BFG97 from CATV PA and if yes is it better same or less drive to next stage eg final c1971
how many milliwat is out from NFG(& and how much from BFG135 or BFG591 .
What about designing an RD15hvf1 fm amplifer to guet some few 15w from the 5w pll ?
Thanks a Lot Jan.
