Outstanding/key items:

• LTC6820 demo board availability is poor for steering module control boxes. Liverpool has 4 on order but delivery has slipped to DEC 20. Four multiplexer boards have been ordered as a backup.
• Tile/vPDU testing status? Current estimate is that vPDUs will be made available for the cold test stands in March/April.
• vPDU vacuum bagging
• Discussion of cable testing at RHUL.
• Planning for LV and HV(?) filtering
• Are shielded cables required inside the detector?
