Sony CFM-140II-internal photos

[babya]

I have taken some photos of the insides of my Sony CFM-140II mono boombox.

CFM-140II tape mechanism, tuner section and main board:

Speakers:

There are 2 speakers in the CFM-140II-a speaker and a small round shaped tweeter.

Notice how the the speakers in the front cabinet are connected to the main board by a connector.

Thanks for taking the effort to investigate.It looks like a pretty clean assembly.I only wish all boxes were so easy to come apart.That's a piezoelectric tweeter.The amount of output from them vary widely from one design to the next.I find the ones that put out a lot usually give a sharp edge to the highs.There are some boxes with Piezos I really like.Actually, I'm going to give Sony props for actually having any sort of tweeter in this box.In such a mini,it would have been tempting to just put nothing behind its facade.Many smaller boxes are made like that.

I have a few boxes with a plastic zip style tuner rack.It would seem to be a simpler way of moving the tuner marker.My small 3 piece Sony CFS-1200 has a rack that snapped in two.Too bad as it is a really pretty box for one of it's type.Though I should have known better,I actually tried to adapt a zip tie Eventually I just put a stop on the end of the shortened rack sacrificing access to the lower frequencies on the radio band.

The AM antenna looks of a decent size.With easy belt access it should be possible to very easily to keep your mini on the road indefinitly.Again thanks for the detailed look inside!

That's how they should have built them all, unfortunately we know otherwise.
