Tuner converter plate coil & IF Transformers T1, T2, T3 alignment:
- Grounded test points E, B, F and tuner in-between channels
- Connect from the "Direct" output to test point C1 and later C2
- Connect from the "RF-IF-Video" output to test point A on the tuner and set the function to CH 4, I kept the probe set to 75 ohm
Adjustments are described below.
Question: the directions often state adjust for maximum or minimum response at the specified marker frequency, I assume I should adjust the specified coil to get the marker to fall on the pictured response curve in the correct place, but I can also adjust to simply get the highest or lowest scope response for the marker, doing this completely messes up the curve.
I will follow up with some pics of where I land for the final IF & Trap alignment.
