Well you better tell that to the Sony service techs who work on
$100,000 tape machines because they do it routinely.

It's much better to get the air circulating so it doesn't
overheat.
Since you don't use compressed air, what _do_ you do to remove
the
dust? It definitely has to be gone.

Vacuum.  While it may make us feel good cleaning our electronics (I
like clean stuff) , or knowing service does it (marketing?),  most
dust is harmless as it lays.  Forced air does require maintenance;
the
fans and the filters.  But filters aren't used much since people
never
clean them and don't think I've ever seen a consumer device with
them.
I would ask Sony not to blow out my set.  You begging for
intermittent
connection failures especially with edge connectors and dip
switches.
I don't have any experience with tape machines, but are the motors
sealed?  Are there many mechanical parts?  I don't know what effect
dust would have on these parts.  I can only speak to connection
devices.  I don't think I'd want compressed air in my deck if I had
one.  But then again, industrial equipment may be designed to allow
that.  We take industrial electronic chassis (switches sealed,
mechanical devices removed) and immerse them in di water for
cleaning.  Sometimes there is a big difference between industrial
and
commercal equipment.

I've seen much more damage from a vacuum wand bumping into components
than damge from a 20 PSI air hose. You just can't clean without
concentrating the air flow with a wand of some sort. Not to mention
you'll finish cleaning the same day you start.

I've been taking my chances with an air hose on electronics for over
30 years and have yet to damage anything. And I, too, work on machines
ranging from 50 bucks to $500,000. The people who pay me trust me.
