The AMP board for this tube has been swapped with a bad one from
tube10.  That board is out for repair; in the meantime one labled
"to be tested" from our spare stock has been installed in tube3.
It appears to be working fine.  Tube3 is up and available for use.

The DTC board from tylan10 was installed.  START3 was loaded and the tube
is firing.  Its progress will be watched to see if any failure happens.
The chips on the board were reseated and the act of reinserting the board
into a slot may have cleared up the i/o problems from tylan10.
tylan3 is up
