I barely found this sony m-430 microcassette-corder and it works for the most part except the sound quality. When I play back anything I’ve recorded it’s mostly just faded voices with an overpowering static sound. Anyone know what I can do? Or is it time to give up? Thank you!
Hi, Try cleaning the pickup head and see if this improves the audio quality. Use a Q-Tip moistened with IPA 90%+ (Isopropyl Alcohol - available at most pharmacies).
It may also be a microphone problem but you would need to do testing of the circuit to try and find out where the noise was emanating from to prove this was the case. Here is a link to the ifixit Sony M-430 Microcassette-Corder Microphone Replacement guide. As the microphone is a sealed unit it most probably cannot be repaired and would have to be replaced if it was the cause of the problem.
