So far I´m a satisfied customer. I have only downloaded "TECHNICS SX-KN470 Service Manual" maybe I will use it later.
Best regards

Good manual. It is complete and of high quality, both text and graphics. The schematics are with the original big size, so it can be viewed or printed without any loss of resulution and sharpness.

ADJUSTMENT
Item 3. Mechanism Adjustment Adjustment Method, Adjustment Value First, reset by pressing both FNC and MODE keys at the same time and boot up the system in Test Mode. Display Setup screen with the FUN key, and press ADJ key for making adjustment. Note 1: If adjustment becomes impossible as a result of having input incorrect values, clear the E2PROM first and then conduct the adjustment. This can be done by resetting while pressing FNC and VOL- keys. When this is done, the machine also loses the mechanical positions. Therefore, this must also be adjusted again. 4. Confirming on the starting points of screen display In MONO Scope screen, confirm that the right and left positions are uniform. If they are off a little, use VR200 (HYOUJI) to adjust the right and left to be uniform. (Adjust to less than one dot difference.) If the difference is much too large, adjust from the beginning of X35 again.

X14 Circuit Adjustment
Item 1. Image Detection Coil Adjustment L29 Adjustment Method, Adjustment Value 1. Turn VR3 (RF-AGC) all the way to clockwise direction beforehand. 2. Impress DC of approximately 2.0V on TP (AF AGC) (IC22 36-pin) 3. Input to TP (IF) (CF3 1-pin) the following: fo=58.75MHz, Mod=1kHz, AM60%, and Level=100dBµ . 4. Observe the waveform of TP (VIDEO) (IC22 8-pin) with an oscilloscope and adjust L29 so that the output level will be the maximum. Condition · ANT no signal · If the waveform is clipped, raise the DC voltage a little. · AC range
