Touching the knob turns off AFT. i.e. the 'Lock'. If you tune to the center of a station while touching the knob, and it goes off frequency when you 'untouch' the knob, then the FM detector is misaligned. See FM Alignment step 1 page 9 of the manual. Voltmeter across R124 (TP101), tuned to a quite spot (no signal) and carefully tweak the backside slug of L101 for zero volts. skip steps 2, 3, and 4 unless you have the proper test equipment.
