I recently received this set (RT225H, SA255H, RP255H) as a gift from my grandfather. But I have no idea how to connect them and how to clean the ports and cables etc. I really want to learn how to clean it and how to use it. Any help would be greatly appreciated.
The turntable connects to the "phono" inputs on the bottom unit. Red = Right channel, White = Left channel. You can see there is a ground connection next to the phono inputs.
The multipin cable goes between the tape deck and the bottom unit where it says "tape"
Yeah, they should go to the line-in/line-out on the tape deck. Which is which is going to take some testing. I would guess red/white are line out and yellow black are line in. But that is just a guess. Use the model numbers and search for user's manual on the internet. There might be one you can download. I didn't find anything in English so I can't help too much more.
