Hello, Can someone please help me with the datasheet of the 1SV196 diode suggested to replace the 1SS83 Yaesu originally put into the RF-unit to switch the filters? I have the original Technical Bulletin about the mod from Yaesu (TB-9643) which quotes this type but web search brought up nothing useful. I need to find some replacement parts for a friend's MP. 73!
