Very good reproduction (copy) of original manual. Didn't have a parts list, but schematic was completely labeled with parts. Complete instructions on how to adjust mechanical functions of the 8-track deck. Well worth having and at a very reasonable cost.

It's a full manual. All the parts are in there. I haven't found the problem yett, but I am working on it; hope I can rebuild the part myself. To make it more secure and unbreakable this time. Because the part has failed several times before and costs a lot to let it be repaired.
Thanks so much for this rich illustrated and parted manual.

I downloaded the document. The manual was complete, well scanned and everything was legible. I could zoom in see what I needed to know. There's not much more that you can ask.

El manual esta muy detallado, los numeros de partes y los esquemas de despiece son correctísimos y muy claros, tanto para los técnicos experimentados como para los novatos.

3.4.1Description of procedure:
3.4.1.1Diagnosis
Check the output frequency of the TCXO using the level-2 testing program for S10. Switch off the �CMD in Use� option in the config file (S6xx.CFG or S611.INI depending on the version of the testsoftware) and restart the program. Start the S10 test, when the program says �Check power and phase of external antenna with your GSM-Tester�, switch the CMD to �LOCAL� mode and enter the �MODULE TEST�. On the CMD display you can see the frequency error of the handset. (Make sure that the CMD is on channel 124, power level 5!) If the frequency error is higher than 2kHz, the TCXO has to be replaced.
3.4.1.2Repair by component change
Use hot air blower to remove defective TCXO. Avoid excessive heat! Watch surrounding components! Resolder new TCXO afterwards.
