I used to service the 2010's. Most of the failures were from user abuse,
such as dropping the set, or substituting the external power supply for one
that was out of specs.

A few common things that would go wrong were the users breaking the antenna.
Another was leaving batteries in the radio and letting them leak, thus doing
damage. Some others were forcing controls and breaking them, dropping the
radio thus causing damage to the tuning control, and or the LCD display.

When putting on an external outdoor antenna, it would be good to take care
for static electricity on the antenna, especially from a thunder shower.
This can cause the main RF input FET devices to be damaged. A protection
unit of some type would be recommended. If the set has poor sensitivity on
the short wave bands, the input FET's are the usual cause. These are very
easy for an experienced service tech to change, and then check the set for
proper sensitivity.

If the set is used with care, and kept in a dry place that is at the normal
room temperature range, it should last a very long time. Never leave weak
batteries inside, and when using an AC adaptor, use the original type, or
one that you are sure that it meets specs. The on board retractable antenna
can be easily broken.

I have one myself that is about 10 to 12 years old, and use it often. The
only thing I did to it was change the mechanical filter to one that is a bit
more narrow for the wideband. I also re-aligned the IF amps and front end
to peak it up. There was not much improvement from re-aligning it, than
from the factory. Infact, I was only able to see the very slight differences
on the instrumentation, but not hear the difference.

The set has very good reception, and is a good performer for the class of
receiver that it is. The sound quality on this receiver is also very good.

I just picked up a 12 year old Sony 2010 in very very nice condition and
working perfectly. With this radio being 12 years old, how many years of
reliable service should it have left. Thanks for any info. on this
subject...I don't really understand the technical stuff behind these radios
and hope the damn thing can run another 12 years and not even blink, but
perhaps that is wishful thinking???
