I'd have to check the books to be sure, but I don't think the 130C had more that one antenna input. They used the MTT module for tuner/control function, and I can't remember ever seeing multiple rf inputs on that module. (But I saw tons of bad connections in those modules!) I think 1987 was the last year for the 130 series. I guess I need to dig out the old manuals, 'cause you got me wondering about it now.
The 130C had a seperate power supply off board to the right of the flyback, because the 130 series was a hot chassis, and this extra supply provided ground isolation for the A/V inputs. They also added some pin correction circuitry to straighten up the sides. I used to see a fair number of those with bad pin driver transistors.
Hey, Jstout66, do you know the model number on the set? Then we'll know for sure.
