Cleared broken wafer.  Jim Kruger did some chamber seasoning following the opening of the system.
Replaced magnet on front door latch.  Replace bulbs in Ready/Remote switch on microwave generator with 382 bulbs (14V, 80 mA).
During venting turbo current increased from 1.85A to 2.20A and foreline pressure increased to about 60 mTorr so the gate valve seems to be holding in the closed position pretty well even if there is atmospheric pressure pushing against it.
