Man, I know this an old thread, but I couldn't help myself. I just discovered and was given an RCA RS177J amplifier. I am also a newbie when it comes to working on anything with tubes; I just know I prefer the sound from a general perspective. I'm currently just looking for pictures of refurbished ones to get an idea where to start since this is going to require rca inputs and new output plugs. Also, any part lists from other rebuild would be great. I'm hoping my sansui AU-517 preamp, or marantz 2238 preamp will be enough to drive it or overcome the gain issues if my aikido struggles.
