An excellent document to assist in the repair of my old personal tape player. It includes full circuit diagrams and physical layout drawings and full instructions on disassembly and fault finding.
Well worth the meagre price.

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.

4. Hot-Keep This function automatically controls the on-off operation of the indoor fan motor in accordance with the on-off operation of the compressor during the heating operation, thereby preventing the air conditioner from delivering a cold air when the compressor is off. When the room temperature exceeds the thermostat line �H1�, the compressor is turned off, and the indoor fan motor is turned off after rotating at �UL� for 30 seconds. 3 minutes after turning off the compressor, the compressor is turned on for 3 minutes. (below thermostat line H01). While over H01, the compressor is off. At 10 seconds after turning on the compressor, the indoor fan motor is turned on. The next compressor OFF time is for 3, 8 or 15 minutes according to the room temperature (the time increases with a rise of room temperature).

6. Overheating protection system When overloading occurs during the heating operation, this system controls the outdoor fan motor according to the indoor pipe temperature to prevent the overloading of the compressor and restrain the rise in high pressure. When the indoor pipe temperature exceeds U1�C, the outdoor fan motor is turned off, and when the indoor pipe temperature falls U2�C, the outdoor fan motor turns on. If three minutes elapse after turning off the outdoor fan motor, the outdoor fan motor is turned on, when the indoor pipe falls U1�C.

Figure Y-9 Table Y-3 Fan speed Line U1 U2 7. Current control This system, in order to prevent overcurrent during heating operation, controls the outdoor fan motor and changes the indoor fan motor speed by detecting total current. When the current exceeds P1, the compressor is automatically stopped. When the current exceeds P2, the outdoor fan motor is automatically turned off, and when the current falls below P4, the outdoor fan motor is turned on. When the current exceeds P3 and the indoor fan speed shifts down because of cold air(5. Preheat air flow), the changes in the indoor fan speed shifts up as follows. OFF UL, UL L And when the current falls bellow P5, the indoor fan speed shift up is canceled.

Figure Y-7 5. Preheat air flow This function is intended to prevent cold air from being discharged when the heating operation starts or when defrosting. When the indoor pipe temperature is below 29�C at the beginning of the heat operation or after defrosting, the indoor fan motor stays. When the indoor pipe temperature gets higher than 29�C, the fan motor is turned on at speed �UL� after compensation of starting. When the indoor pipe temperature exceeds 35�C, the specified fan speed is restored. When the indoor pipe temperature falls below 30�C, the fan speed shifts down to �UL�. And, when the indoor pipe temperature falls below 24�C, the fan motor turns off. Then, over 29�C , it turns on again at speed �UL�.
