I have this tape recorder. My father bought this RX1750T in the year 1982. Now it is year 2020 and this tape recorder is still giving me service. I love this tape recorder. It was purchased from Aizawl, Mizoram, India.
Great job restringing the AM/FM tuner. However, you didn't repaint the speaker grill or blacken the woofer. Should've cleaned the clear plastic that goes over the cassette door too. Overall a decent job but I think you have the talent to do better.
