Belt replacement

One of the issues with any tape recorder and many vinyl record turntables is that the drive belts perish and degrade over time.

This is true for any of the Walkman and other similar players, and often these belts need to be replaced.

It is not difficult to find replacement belts as they are stocked by a number of different companies and these can normally be easily located on the Internet. The cost is also not particularly high.

Some of the earlier Walkmans were assembled using screws and these are easy to disassemble to gain access to the belts.

However the EX150 was one of the later units and it was manufactured to a cost. This means that getting into them can be a challenge.

The assembly of the outer casing used press fit clips on the plastic mouldings to clip the casing together and there is no easy way to disassemble the unit.

Often the only way to get into the unit is to pull the two sides apart and this can result in breaking a good number of the clips.Any disassembly should be done with care to preserve as much of the integrity of the case as possible.



The Sony Walkman WM-EX-150 is a great little cassette player and ideal for many uses even today. Like all units of its age,some maintenance may be needed, but they sell for a reasonable cost ont he second hand market and most of them should work very well.
