Saturday afternoon made the input block attached to the KRK12C tuner using the dimensions from the CT-100 manual. The RF sweep signal is applied to the mixer diode in the tuner and using and alligator clip there is awkward. The input block position is reinforced with a sprung clamp around a transformer can a well as the two phenolic pins with straddle two holes on top of the tuner.
This will be used to perform the IF alignment and chroma channel as well as facilitating full sweep tests as outlined in the RCA Service manual.
Now on to the testing and alignment this week.
