The carrier pot wiper fell out of my R-390 and I have been having trouble
locating a new16 ohm pot. I put in a 100 ohm 10 turn pot and then zero'd
the meter. I then removed the pot and ohmed it out. It measured 8 ohms.
I had a 7.5 ohm resistor in my junque box so, what the hell. I soldered it
up and my meter sits exactly on zero when I turn the rf gain all the way
back. I am thrilled and plan to keep it in place. I may put the pot in
just for
looks. Nobody will ever know. So there is my 16 cent science project for
the day. I can now use my 390 without the needle pegged against the 100
stop.
AES used to sell a 16 ohm pot but no longer stocks them. Fair stocks
them but
they are used. Who knows how long it will last.
