Sams lists a CLOSE model #TRC25BK. Its in Sams TR45. TR series Sams are
separate books that will have many different models.
First easy thing is to clean the PB/Rec switch. They are usually Alps switches

guess half of the cassette decks. Lots of symptoms !
After that a recap would probably fix it.
