T102 is the 4.5 MHz trap adjustment. It's located inside a metal shield. To adjust, tune in a strong signal and set the contrast to maximum. Adjust the fine tuning until a beat patten is visible on the screen. Adjust T102 for minimum beat interference.

The sound IF coil is T201 and is located next to the audio IF/output IC201. To adjust, tune in a station and adjust for maximum sound. Reduce the signal strength at the antenna terminals until distortion appears. Continue reducing signal strength while adjusting T201 for minimum distortion.
