I'd like to thank those of you who sent me Email about 
my ailing SE.

I pulled out the power supply last night and checked the
outputs with a voltmeter.  

The 2 +12V lines and the 5V line were about 14 and 6 volts
respectively while the -12V line was only about -8V.

So, do I buy another power supply or maybe try a "lab"
supply to see if something else might be wrong?

BTW, what is the -12V used for?  The power supply label 
says that the 2 +12V lines are for the disk and sweep.
I assume the +5V line runs the silicon.
