cara mengepaskan frekuensi kenwood tr 9000 yang geser

looking for the location of the frequency adjuster, but couldn't find the manual book, finally got the info for the adjuster, there is VR 1 = 100K, VR2 = 10K, this is for fine tuning the frequency, in principle, if it deviates too much above R27 = 10K, the value is reduced, if the frequency is too low from the display screen, R27 is enlarged
