Very good conversation, Pretty fast Service, wood do it again,
Have paid by Paypal, so i got the Service Manual online after 15 Min.
Greeting from Germany,
Good-quality scans. Detailed description. I hope I can repair the machine.
High-quality scanning. Detailed description. Recommend for all technician. A+++
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!

8. Tape Speed Adjustment (DECK 2) Settings : â¢ Test tape : TTAâ100 â¢ Test point : TP8(Lch), TP9(Rch) â¢ Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000Hz Â± 5Hz (FWD) and FWD SPEED Â± 45Hz (REV). 9. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : â¢ Test tape : TTAâ330 â¢ Test point : TP8(Lch), TP9(Rch) â¢ Adjustment location : Azimuth adjustment screw Method : Play back (FWD) the 8kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode. 10. PB Frequency Response Check (DECK 1, DECK 2) Settings : â¢ Test tape : TTAâ330 â¢ Test point :TP8(Lch), TP9(Rch) Method : Play back the 315Hz and 8kHz signals of the test tape and check that the output ratio of the 8kHz signal with respect to that of the 315Hz signal is within 5dB. 11. PB Sensitivity Check (DECK 1, DECK 2) Settings : â¢ Test tape : TTAâ200 â¢ Test point : TP8(Lch), TP9(Rch) Method : Play back the test tape and check that the output level of the test point is 110mV Â± 3dB.
12. REC/PB Frequency Response Adjustment (DECK 2) Settings : â¢ Test tape : TTAâ602 â¢ Test point : TP8(Lch), TP9(Rch) â¢ Input signal : 1kHz / 8kHz (LINE IN) â¢ Adjustment location : SFR351 (Lch), SFR352 (Rch) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP8, TP9 becomes -20VU (-26dBV). Record and play back the 1kHz and 8kHz signals and adjust SFRs so that the output of the 8kHz signals becomes 0dB Â± 0.5dB with respect to that of the 1kHz signal. 13. REC/PB Sensitivity Check (DECK 2) Settings : â¢ Test tape : TTAâ602 â¢ Test point : TP8(Lch), TP9(Rch) â¢ Input signal : 1kHz (LINE IN) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP8, TP9 becomes 0VU (-6dBV). Record and play back the 1kHz signals and check that the output is -2dB Â± 3.5dB.
