[R-390] Noise when warm ('390A)

[Barry]

Is you radio located near a kitchen?  If so, do you listen early in the
morning?


My radio does the same thing sometimes.  I always attributed it to a
capacitor, but I recapped all the paper caps so I'm not sure.  Someone
suggested the VR tube.  Maybe I'll check that out on mine too.

Hi everyone,

      I've noticed lately that after a few hours of operation, a
"frying bacon" or "snap-crackle-pop" noise begins to occur, slowly
increasing as time goes on.  No real difference in band or mode.

      Any quick troubleshooting hints to isolate to a stage?

      What is the consensus...more likely a cap or a tube?

            Thanks for the advice,

           Dennis
