Vintage Nikko Stereo Amplifier TRM-400 Works Very Nice Condition made in Japan . Condition is Used. Hello, up for sale I have older Nikko amplifier, its in very good cosmetic condition with normal age wear and few small scratches, its turning on and all of the knobs and buttons work good, I got it from a guy and he told me that he doesn't even remember if he used it or not, and if you look at the cord it kind of looks like its factory wrapped, but thats just a guess, plea...se look at the pictures as they are part of my description and if you have any questions let me know, thanks for looking and good luck bidding. Because of the weight I might ship with FedEx as well, thanks again.
