Introduction

Somehow I acquired yet another Sony cassette deck. There is nothing much to do initially but I will detail all service operations in the following articles.

Disclaimer
The following articles are not to be treated as do-it-yourself tutorials on how to fix, restore, rebuild, or improve the unit in cause. This was not my initial intention. But you can consider this whole content as a general guideline, should you decide to launch into such an adventure.

The entire documentation is just a reflection of my work and I cannot be held responsible if you damage your unit, or even harm yourself in the process.
