An early 1970’s amp by Trio now more commonly known as Kenwood It has been tested and source inputs work on both left and right channels. The headphone output works and I was surprised by the sound quality, especially since I was using an old personal cassette player to test it. There is plenty of crackle on the dials, I have applied some contact cleaner and it improved greatly but there is still some crackle, it should go away with use. All dials and switches work. The faceplate has some cosmetic wear and staining but with some good cleaner it should come up nice. The casing edges has some bends on the corners. It’s very dusty inside so could do with a good service . It has a new plug fitted.
