I cannot find D75 on this superstar 3900 board. I've spent countless hours looking and reading the schematic sheet. I'm tring to do the clarifier mod It says its near the VR15, but this radio does not even have this either. Need help.

Hmm. A duplicate post? See the other one labeled "Superstar Grant". Should be the correct info for your radio. Pretty sure "D75" refers to a totally different radio chassis.

Hello if its the same year as mind its not the diode you want that was cliped to give talk back
in my radio. do you know your way around in a radio at all just follow your wires back from the pot and use a vtm to get the high side then go find a unswitched voltage you need. Buy the way
you will need to retune all your offsets am usb lsb got a freq counter ?
