On the final part of our flight; when we were fairly close to our destination; we witnessed the ADF frequency box let out a stream of smoke. I immediately shut it off and instructed the first officer to pop the circuit breaker. Verified with the checklist. The smoke stopped; but the smell lingered before subsiding. Since the box was on an isolated area on the panel and it immediately stopped smoking; I did not declare an emergency and return to the departure airport. We were also outside the USA at the time in a remote area; so the only suitable airport for us would be our base airport; so we elected to have the inspection done at our base.
