   This, well, very little dorabotochka,
help you avoid burnout during VG93
the absence of any of the stress
applied to this LSI. In the absence of
of stress I am not crash VG'shka
I know, because never experienced this.
In one clever book is written - which, when
the absence of a 12-volt ... But it's not important.
In general, quickly put this shemku and
forget about it forever after burning
VG'shkah! Revision, it is better to collect from
reverse side of the board - so beautiful (in
Pentagon'e, at least). Well
finally say that specifically tested
this scheme - works as it should!
