Re: Apple 2gs monitor

Where safety is concerned there are some EXTREMELY important points to
remember:
1) The picture tube will store a very high voltage (up to 25,000 volts) for
up to a month before bleeding off a charge.

2) The picture tube should ALWAYS have the Anode voltage bled off before
servicing.  Connect one end of a clip lead to the spring that goes around
the outside of the picture tube and the other end to a long flat bladed
screwdriver that it worked into the anode connection (the big RED wire at
the top of the tub).  Caution:  It will make a spark you can see and hear,
so do do this if you are a jumpy type.

3) Even after the picture tube is shorted out, it can restore a partial
charge on its own so always short out the tube before reconnecting the
anode lead.

4) If you don't feel confortable with doing this, DONT DO IT!  The life you
save will be your own.

5) The neck of the pix tube is extreme fragile, so try to keep your hands
and arms out of the area of the neck.  If you break the neck, the tube is
history!

I have been working on televisions and monitors for over 25 years.  I am
extremely safety concious and even in my best efforts, I have been shocked,
one time almost losing my life.  If it can happen to me, you can surely bet
it can happen to you.  I even had a monitor shock me from 18" away, one of
those strange but true stories!

Sorry to make a long message, but I feel than everyone should know what the
dangers are ahead of time.  Dont need any Apple II users dying on us.
