Please, help identify thump sound
Hi all,
my father-in-law is getting a thump,thump,thump sound 1 to 2 times in a song and then may not here it again for like 3 songs later. now, let me explain when he is getting this. it is happening ONLY when he records a vinal to cassette tape,its only coming out on the play back of the tape. he will not here it while the record is being played,but again, its coming out on the tape when played back.
weve tried replacing one component at a time, then all components at once. its still there on recordings. items we tried to replace are , record layer,reciever,tape deck, all new wires except speaker wire,which at least looks to be fine. nothing has changed at all when problem started.
what could be causing this ???? it it the electric?? some piece of equiptment in the house or maybe a nieghbors?? he does have the socket overloaded and has a cheesy multi plug in outlet type box.
Help??
thank you
Tim
