my model 12 has developed what seems to be a power supply problem...
 
one day i went to power up the machine, and all of the lights on the
front (disk drive led, power on light, etc) began to flicker, and the
power supply made a clicking noise.  modern troubleshooting techniques
says this is the result of a short on one leg of the power supply, but
the question is where is it??
 
before i tear the machine apart down to the frame, what i need to know
is what is the common cause of this problem??  (ie. weak spot in
the design, as i don't like dissecting machines any more than i have
to.)

i'm going to have a big problem if i can't get this machine working
because my entire cp/m archive is on dsdd p&t disks, which seem to be
unreadable in every other machine i've found.  (except, of course, another
model 12.)
