I know someone with a early 60's plymouth, I tried to repair the mopar am/fm radio a while back, the mixer osc transistor is dead, but its a sk3018 4 pin to18 type metal can device.
I tried a couple of alternatives, but with it being germanium and used as a mixer/osc is difficult to replace.
Any ideas on what I could do to sort this old radio out, being the original my mate wants to keep it.
(I thought he'd sold the car and mentioned this on another thread, but apparently not).
