- The machine is not EE tape compatible!
- The headstocks of the Technics_RS-1500_US and the Technics_RS-1506_US can also be used on the RS-1700. The RS-1700 automatically detects these headstocks and disables autoreverse operation. When using the RS-1500 head mount (RP-2224), two-track recording is also possible with the RS-1700. To get the original head mount (RP-2R2R) as a spare part is almost impossible even on ebay.
- Typical signs of age:

The looping causes the key control to shut down and cannot be used again until the tape is retightened. You can remedy this by replacing the old felt brake pads with suede. How to do this is described in detail at [Tips for repairing Technics RS tape machines].
