【Product Operation: Refurbished and Working】
After refurbishing, operation has been confirmed with an external AA battery box. The battery case latches are in good condition.
There are no signs of battery leakage, and the battery terminals are shiny and clean.
The crucial pinch roller has been replaced with a new one, so there are no dents, smooth or shiny surfaces, and it performs perfectly.
The playback sound is clear, with no excessive noise, and it can reproduce very good sound.
Playback, stop, fast forward, rewind, and reverse (invert) have been tested for a long period of time.
The playback speed of FWD and REV is stable and normal, and the speed difference has been measured and confirmed to be within an acceptable range.
There is no noticeable sound fluctuation, and the wow and flutter measurement results are good.
All operation buttons and selector buttons on the main unit have been tested.
The volume control does not make any crackling noises.
It also has a 3.5mm standard earphone jack, so you can enjoy it with commercially available earphones.
Please refrain from using tapes longer than 90 minutes, severely deteriorated tapes, or low-quality tapes from overseas, as this may cause sound fluctuations, playback failure, or malfunction.
