This is a good quality scan of the original Service Manual from Nordmende, Germany. Contains the circuit diagram, PCB layout, adjust/tune instructions as well. It is NOT in English but in GERMAN language! That was quite right for my german friend from the lower east side in Berlin.

Received via e-mail this PDF manual is worth the money. This is a quality scan of a manual in excellent condition and is just as good as having the original manual in hand. I have later seen the original manual and it was printed in colour, but this particular manual is black & white but scan resolution is high end quality! All drawings and pictures are presented in great detail. So, nearly perfect score in my opinion.
If you own the turntable you also should own the manual!

ADJUSTMENT
X25 Circuit Adjustment Specification (M : For the Other Markets) Item
1. Video detection co il adjustment L303
Adjustment method/Adjustment value
1. Turn VR301 [RF-AGC] fully to the right. 2. Apply DC2.0V to TP [IF AGC] (IC300 pin36). 3. Feed fo=38.0MHz, Mod=1kHz, AM60%, Level=100dBµ into TP [IF] (A100 pin8). 4. Observe the TP [VIDEO] (IC300 pin8) waveform on an oscilloscope and adjust L303 for maximum level.
Conditions
No ANT signal If the waveform is clipped, slightly increase the DC voltage. AC range
Maximum
2. Audio detection coil adjustment L300
1. Turn VR301 [RF-AGC] fully to the right. 2. Feed fo=31.5MHz, No Modulation, Level=94dBµ into TP [IF] (A100 pin8). 3. Connect a voltmeter to TP [SIF] (both ends of R314) and adjust L300 for 0V ± 0.01V.
No ANT signal
3. S-METER adjustment VR300 4. RF AGC adjustment VR301
1. Turn VR301 [RF-AGC] fully to the right. 2. Feed a 30dBµ CHINA 9CH color bar RF signal into the ANT input terminal. 3. Audio (P/S ratio -6dB) no modulation. 4. Connect a voltmeter to CN300 and adjust VR300 [SMET] so it reads 3.5V ± 0.05V. 5. Set the RF signal to 70dBµ and adjust VR301 [RF-AGC] so that the voltmeter connected to CN300 reads 4.8V ± 0.05V.
Postpone adjusting VR301 to prevent AGC having effect at 30dBµ. Ensure the RF AGC adjustment is performed after the S-METER adjustment. No ANT signal Test mode
5. Diversity free run frequency adjustment VR400
1. Connect a frequency counter to CN400. 2. Using the remote control unit TV/NAVI button, switch to adjustment mode. 3. Adjust VR400 [15kHz] so as to obtain 15625 ± 100Hz.
