You shoud have the same peak-to-peak waveform on both sides of C135, just different DC. If that's what you have, C135 is OK. This is the same AC waveform on all the color difference amplifier cathodes. Look at the waveform shown on the R-Y ampifier cathode. It is 15 v pp including both the blanking pulse and the signal, so I'd guess 10v pp for the pulse alone is OK.
