[time-nuts] pts 160 power problem

hi

i recently bought a pts160.  when first turned on, the 5v was pulled quite
low: < 3v.  after an hour or so, the condition cured, the 5v = 5.1v and the
output matched the decades.
then, it died again.  so i know there is a unit worth saving.

i tried another more robust 5v supply, but that goes to 4.5v and ng output.

i removed each of the plug-in decades, one at a time, looking for the guilty
one.  no joy.  i also removed the left rear module (uses 5v).  the other two
modules only use 12v. which is fine.

has anyone been here before?  could it be a problem in the backplane (a work
of art, btw)?

many thanks...

dave
