When I got my first KCS-47 way back when, it had a quadruple-image problem. There is a molded capacitor across two terminals of the horizontal oscillator coil can, it's what caused me to re-cap my chassis! The adjustments described above will not help if this cap is bad. I've even seen this problem covered in a (legendary) Jack Darr TV-repair book! It's a .01, I think. It's the same color and about half the length of a piece of a Bit O' Honey candy. Molded from what, I don't know, but it leaked down to the kilohm stratum, especially when I held a flame nearby. This was in 1985, when it was barely 35 years old! Just put in a nice, trusty Orange Drop rated @400-600V and tweak the ringing/stabilizer/sine wave coil (whatever it's called in your service literature). Worked great for me!
